Bacillus spp. have been used against diseases caused by bacteria that affect cultured shrimp, providing beneficial effects on the host shrimps by altering their microbial community, and improving zootechnical indexes. The objective of this work was to evaluate the effects of a diet supplemented with Bacillus cereus-a bacterium with probiotic potential-on post-larvae Litopenaeus vannamei shrimps grown in laboratory. The experiment lasted for fifteen days and consisted of six treatments-control (T1), probiotic (T2), Vibrio parahaemolyticus (VP) (T3), probiotic and VP (T4), V. alginolyticus (VA) (T5), and probiotic and VA (T6). The survival rate, weight gain, colonization capacity of the probiotic bacteria, pathogen count, and histopathological lesions were evaluated. There was no significant difference (p=0.05) in survival between treatments. The groups with pathogens and without probiotics presented lower weight gain. The result of the Bacillus cereus count in the treatments T2, T4 and T6 were significantly different (p

As lesões coronarianas já foram relatadas em espécies de peixes anádromos, com características semelhantes às observadas em aterosclerose humana, mas não em peixes cultivados sem interferência de padrões reprodutivos. Objetivou-se descrever lesões coronarianas em beijupirá (Rachycentron canadum) criado em sistema offshore, em 54 exemplares coletados ao longo do cultivo de oito meses. Amostras de tecido cardíaco de alevinos e juvenis foram submetidas à análise histopatológica e à microscopia eletrônica de transmissão (MET), para visualização de lesões coronarianas, sendo as lâminas histológicas coradas pela técnica de hematoxilina-eosina, ácido periódico de Schiff, alcian blue e reticulina de Gomori. Exames realizados pela fotomicroscopia de luz evidenciaram lesões arteriais caracterizadas por hiperplasia das túnicas íntima e média de artérias coronárias em, respectivamente, 29,63% e 79,63% dos animais, com redução do lúmen arterial. Na MET, foram observadas alterações na estrutura das coronárias com espessamento do endotélio e membrana basal, proliferação de fibroblastos e fibras colágenas, com acúmulo de material lipídico subendotelial, resíduos celulares aderidos à membrana basal e vesículas pinocitóticas com presença de lisossomos isolados. Constatou-se que os peixes da espécie Rachycentron canadum criados em cativeiro desenvolvem lesão arterial do tipo crônica degenerativa inflamatória. The coronary lesions have been reported in species of anadromous fish with similar characteristics as those observed in human atherosclerosis, but not in farmed fish without interference of reproductive patterns. This study aimed to describe coronary lesions in beijupirá (Rachycentron canadum) farmed in an offshore system, in 54 specimens collected along an eight month cultivation period. Samples of heart tissue of fry and juveniles were subjected to histopathological analysis and transmission electron microscopy (TEM) for visualization of coronary lesions, the histology slides were stained using hematoxylin-eosin, periodic acid Schiffh, alcian blue, and reticulin of Gomori. Examinations performed by light microscopy showed arterial lesions characterized by hyperplasia of the intima and media tunics, respectively in 29.63% and 79.63 % of the animals, with reduced lumen. In TEM changes in the structure of the coronary endothelium and thickening of the basement membrane, proliferation of fibroblasts and collagen fibers, with subendothelial accumulation of lipid material, cellular debris adhering to the basement membrane and presence of pinocytotics vesicles and isolated lysosomes were observed. It has been found that the Rachycentron canadum fish species farmed in captivity develop arterial lesion of the chronic inflammatory degenerative type.

The Burkholderia mallei is listed in the list of the World Organisation for Animal Health (OIE) as an important public health disease, and due to its high potential for infection is referred to as a bioterrorism agent. According to the OIE comprises the serological diagnosis, allergy testing and bacterial isolation, and complement fixation, the official test to be performed for trade of animals. This method of diagnosis is recommended in Brazil by Instruction Nº 22, 16 of march of 2018, Ministry of Agriculture, Livestock and Food Supply by its high sensitivity and specificity. According to the OIE comprises the serological diagnosis, allergy testing and bacterial isolation, and complement fixation, the official test to be performed for trade of animals and bacterial isolation is considered gold test for identification of the agent. From the bacterial isolation the presence of Burkholderia was identified in 11 samples from epidemiological surveillance in the disease outbreaks. Sequencing demonstrated the circulation of the strains Burkholderia pseudomallei and Burkholderia mallei in Brazilian territory where Mormo is present. The results show the differentiation of the circulating strains in the national territory and provides the knowledge of their epidemiology and virulence, later assisting in formulations of disease control and eradication measures O Mormo constitui-se em uma doença altamente contagiosa dos solípedes causada pela Burkholderia mallei, uma bactéria Gram-negativa, não móvel e cocobacilo aeróbio, infectando primariamente equínos, asininos e muares, entretanto humanos são considerados hospedeiros acidentais. Burkholderia mallei está relacionada na lista de doenças da Organização Mundial para a Saúde Animal (OIE) como doença de importância de saúde pública, e devido ao seu alto potencial de infecção é referenciada como agente de bioterrorismo. De acordo com a OIE o diagnóstico compreende o teste sorológico, alérgico, isolamento bacteriano e testes de biologia molecular, sendo a fixação do complemento, o teste oficial a ser realizado para trânsito de animais. O Ministério da Agricultura, Pecuária e Abastecimento, através da Portaria Nº 22, de 16 de março de 2018 do Ministério, utiliza o teste da Fixação do Complemento e Elisa para triagem dos animais, sendo aqueles reagentes, testados posteriormente com o Western Blotting para confirmação. Neste trabalho, temos como objetivo identificar filogeneticamente as cepas circulantes em território nacional para os animais suspeitos de Mormo. A partir do isolamento bacteriano foram identificados 08 resultados compatíveis com a Burkholderia em amostras oriundas de vigilância epidemiológica em áreas focos da doença. O sequenciamento demonstrou a circulação das cepas Burkholderia pseudomallei e Burkholdeia mallei, em território brasileiro onde há presença do Mormo. Os resultados mostram a diferenciação das estirpes circulantes em território nacional e proporciona o conhecimento de sua epidemiologia e virulência, auxiliando posteriormente em formulações de medidas para controle e erradicação da enfermidade.

Its immunostimulatory role has already been proven in several studies, protecting shrimp by activating several factors present in its immune system and conferring greater resistance to infection. Among these agents, White spot syndrome (WSSV) and Infectious myonecrosis (IMNV) viruses have historically already caused billionaire losses and are still widespread worldwide, including Brazilian shrimp-producing states. Our objective was to evaluate the effect of the use of biofloc technology on experimentally infected marine shrimp by WSSV and IMNV. The animals were divided into three treatments, one with WSSV (W) immersion infection, another with infection by IMNV contaminated tissue (I), a third by the two anterior (IW) and the negative control (C), without viral challenge. At the end of the experiment (day 20), the mortality rate did not differ statistically between any groups. PCR analysis showed no positivity for WSSV in any sample, but there were positive animals for IMNV in treatments C (23.8%) and W (8.7%). However, no animal presented macro and microscopic alterations, indicating the non-development of the infection. These results point to a resistance to infection by the animals, suggesting that bioflocs can act as a barrier against infection. A tecnologia de criação de camarões em sistema fechado com bioflocos (BFT) vem se mostrando uma alternativa para evitar surtos recorrentes de doenças infecciosas exóticas.O papel imunoestimulante dele já foi comprovado em vários estudos, protegendo o camarão por meio da ativação de diversos fatores presentes em seu sistema imune e conferindo uma maior resistência à infecção. Dentre estes agentes, os vírus da Síndrome da mancha branca (WSSV) e da Mionecrose infecciosa (IMNV) historicamente já causaram perdas na casa dos bilhões de dólares e hoje estão difundidos em todo o mundo, incluindo os estados brasileiros produtores de camarão. Nosso objetivo foi avaliar o efeito do uso da tecnologia de bioflocos em camarão marinho infectado experimentalmente pelo WSSV e IMNV. Os animais foram distribuídos em três tratamentos, sendo um com infecção por imersão pelo WSSV (W), um segundo com infecção via ingestão pelo IMNV (I), um terceiro pelas duas vias anteriores (IW), além do controle negativo (C), sem desafio viral. Ao final do experimento (dia 20), a taxa de mortalidade não diferiu estatisticamente entre nenhum grupo. A análise por PCR não acusou positividade para WSSV em nenhuma amostra, porém houve animais positivos para IMNV nos tratamentos C (23,8%) e W (8,7%). No entanto, nenhum animal apresentou alterações macro e microscópicas, o que indica o não desenvolvimento da infecção. Estes resultados apontam uma resistência à infecção por parte dos animais, sugerindo que os bioflocos podem agir como barreira contra a infecção.

Thus it aimed to evaluate the effects of adding mycotoxin adsorbents in broiler diets naturally contaminated with aflatoxin and fumonisin, on the parameters: histopathology, biometric and serological. The experiment was conducted with 60 birds, seven-day-old Cobb commercial line in three treatments: T1 - control (not including mycotoxin adsorbents in diet); T2 - adding 0.5 kg / t. of adsorbent A and T3 inclusion of 1.5 kg / t of adsorbent B. The broilers receive in all treatments, isonutritives diets naturally contaminated by mycotoxins. These broilers were raised up to 60 days old when was made serology tests for NDV and IBDV, and after were sacrificed for histopathologic and biometric analysis. The results were submitted to analysis of variance (ANOVA) with significance level of 5% probability and Tukey test. There were significant differences between treatments (P

They are usually treated with antibiotics, which in excess may lead to bacterial drug-resistance. Antibiotic residue can also reach the wild fish or other animals, fish farmers and fish consumers. In this study it was aimed to identify, by biochemical and molecular tests, potentially pathogenic Gram-negative bacteria multi-resistant to antibiotics and potentially probiotic Gram-positive bacteria isolated from farmed cobia intestine in different periods of the year. Ten fingerlings and 30 juveniles were collected, of which 82.5% showed evidence of bacterial infection and 47.5% of nephrocalcinosis. Biochemical and molecular identification results agreed in 86.11% of the 72 Gram-negative strains isolated. There were identified 18 species, 12 genera and five families, Aeromonaceae, Neisseriaceae, Pseudomonadaceae, Vibrionaceae and Enterobacteriaceae, the last one being more significant (63.88 %). The most frequent species were Enterobacter cloacae (27.78%) and Photobacterium damselae subsp. damselae (25%), greater pathogen to cobia. Antibiogram showed that 95.83% of the strains were penicillin resistant (6,25 μg), 62.50% ampicillin resistant (10 ug) and 15.28% enrofloxacin resistant (5 ug). Antibiotic multi-resistance was detected in 69.44% of the strains tested and E. cloacae achieved the highest MAR rate (0.8571). Regarding Gram-positive bacteria, 53 strains were obtained and classified in 13 species of the families Enterococcaceae, Paenibacillaceae, Staphylococcaceae, Streptococcaceae e Bacillaceae. Bacillus cereus was the most frequent species (39.62%) and Bacillaceae the most representative family. Antibacterial activity was observed in 16.98% of the strains, which produced inhibition zones ranged from 9.33 ± 0.58 to 28.77 ± 0.25 mm against Vibrio vulnificus, V. parahaemolyticus and V. alginolyticus. Species presenting antibacterial activity were Staphylococcus piscifermentans, S. lugdunensis, Bacillus spp., Enterococcus spp., E. faecium and Lactococcus lactis subsp. lactis. Of these, E. faecium was the most significant species (33.33%) producing the largest inhibition zones especially against V. vulnificus. Period of year was not significant (P ≥ 0.05) for cobia’s intestinal bacterial diversity, multidrug resistance of Gram-negative, or to the quantity of Gram-positive with antimicrobial properties. Intestine from R. canadum contains Gram-negative bacteria multi-drug resistant and potentially pathogenic to aquatic animals and humans, and Gram-positive bacteria with antimicrobial activity against vibrios, which must be considered as a prophylactic and/or therapeutic alternative against vibriosis in cobia farming. A ocorrência de doenças bacterianas representa restrição à expansão do cultivo intensivo de beijupirá (Rachycentron candum) em tanques-rede e são tratadas normalmente com administração de antibióticos, que usados inadequadamente podem provocar o desenvolvimento de bactérias resistentes, chegar aos peixes selvagens, outros animais e afetar piscicultores e consumidores do produto. Objetivou-se identificar a diversidade bacteriana Gram-negativa, potencialmente patogênica multirresistentes a antibióticos e Gram-positiva, potencialmente probiótica frente a Vibrio spp., isoladas do intestino de beijupirá cultivado offshore sob influência de distintos períodos do ano. Foram coletados dez alevinos e 30 juvenis, dos quais 82,5% exibiram indícios de infecção bacteriana e 47,5% de nefrocalcinose. Das 72 linhagens Gram-negativas identificadas por bioquímicos, 86,11% apresentaram concordância com a classificação molecular. Foram descritas 18 espécies, 12 gêneros e cinco famílias, Aeromonaceae, Neisseriaceae, Pseudomonadaceae, Vibrionaceae e Enterobacteriaceae, sendo a útima mais representativa (63,88%). As espécies mais frequentes foram Enterobacter cloacae (27,78%) e Photobacterium damselae subsp. damselae (25%), maior patógeno do beijupirá. 95,83% dos isolados foram resistentes à penicilina (6,25 μg), 62,50% a ampicilina (10μg) e 15,28% a enrofloxacina (5 μg). 69,44% foram multirresistentes aos antibióticos e a linhagem com maior índice de resistência múltipla a antimicrobianos (MAR) foi da espécie E. cloacae (0,8571). Com relação às bactérias Gram-positivas, foram isoladas 53 linhagens classificadas em 13 espécies, pertencentes às famílias Enterococcaceae, Paenibacillaceae, Staphylococcaceae, Streptococcaceae e Bacillaceae, sendo a última mais representativa na qual inclui Bacillus cereus, a espécie mais frequente (39,62%). 16,98% dos isolados apresentaram atividade antibacteriana, produzindo halos de inibição que variaram de 9,33 ± 0,58 a 28,77 ± 0,25 mm, frente ao Vibrio vulnificus, V. parahaemolyticus e V. alginolyticus. As espécies com atividade antibacteriana foram Staphylococcus piscifermentans, S. lugdunensis, Bacillus spp., Enterococcus spp., E. faecium e Lactococcus lactis subsp. lactis. E. faecium (33,33%) foi a espécie mais representativa, incluída no gênero Enterococcus spp. responsável pelos maiores halos de inibição especialmente frente ao V. vulnificus. O período do ano não influenciou significativamente (P ≥ 0,05) na diversidade bacteriana intestinal do beijupirá, na multirresistência das Gram-negativas, nem no número de Gram-positivas com propriedades antimicrobianas. O intestino do R. canadum inclui bactérias Gram-negativas potencialmente patogênicas para animais aquáticos e humanos, com elevadas taxas de multirresistência aos antimicrobianos testados, Gram-positivas patogênicas oportunistas para humanos e linhagens com atividade antimicrobiana frente à víbrios. As espécies Gram-positivas identificadas são consideradas probióticas para outras espécies de peixes e após os resultados encontrados nesse estudo, potenciais probióticas para beijupirá como alternativa profilática e/ou terapêutica frente às vibrioses.

In this sense, we applied the Loop Mediated Isothermal Amplification (LAMP) technology in order to investigate the possibility of reservoirs or carrier of Whit Spot Syndrome Virus (WSSV) in Paraíba River, in Paraíba Valley – PB. Were selected eight (8) sampling points on the river, near sources of water used by shrimp farms of the species L. vannamei. At each point, 10 specimens of Paleomon pandaliformis, 10 Pomacea lineata, and 10 Melanoides tuberculatus, were collected. These animals were stunned by thermal shock and shrimps had the nerve cord cut, in order to proceed with the collection for LAMP use. Gills fragments were removed from the shrimps, foot muscles fragments from P. lineata and the species M. tuberculatus were collected entire and all samples were stored in microcentrifuge tubes with 95% ethanol (1:10) .The analyses were performed in the laboratory of molecular analyses of Potiporã - RN and all samples were submitted to LAMP (LAMP Kit WSSV, Concepto Azul, Ecuador) for detection of WSSV. In the end, 81 samples of P. pandaliformis, 40 samples of M. tuberculatus and 26 samples of P. lineata were obtained, and positive reactions were observed in 29%, 48% and 8% respectively. IN conclusion, the results confirmed the WSSV presence in wild crustaceans and molluscs, which constitute a reservoirs or carrier of this agent, and a potential risk to local shrimp farming. This is the first report of WSSV in wild M. tuberculatus and P. lineata. A expansão da carcinicultura no Brasil, especialmente no Nordeste, passa por uma mudança no ambiente de cultivo, no qual camarões marinhos da espécie Litopenaeus vannamei, estão sendo cultivados em água doce, cujos desafios sanitários precisam ser dimensionados. Diante disso, buscou-se por meio da utilização da técnica de Loop Mediated Isothermal Amplification (LAMP), realizar estudo sobre possíveis reservatórios e/ou vetores para o Vírus da Síndrome da Mancha Branca (WSSV), no Rio Paraíba, no Vale do Paraíba – PB. Foram estabelecidos oito (8) pontos de coleta nas margens do rio, próximos a pontos de captação de água de fazendas de cultivo de L. vannamei. Em cada ponto foram coletados 10 espécimes de Palaemon pandaliformis, 10 de Pomacea lineatae e 10 de Melanoides tuberculatus. Esses animais foram insensibilizados por choque térmico e os camarões tiveram o cordão nervoso cortado para que se prosseguisse com a coleta de material para utilização da LAMP. Foram retirados fragmentos de brânquias dos camarões, fragmentos da musculatura do pé dos P. lineata e, da espécie M. tuberculatus, foram coletados os indivíduos inteiros, sendo armazenados em tubos de microcentrífuga com etanol a 95% (1:10). Os exames foram realizados no laboratório de análises moleculares da Potiporã – RN e submetido a LAMP (Kit LAMP WSSV, Concepto Azul, Equador) para a detecção do WSSV. Ao final, examinaram-se 81 amostras de P. pandaliformis, 40 amostras de M. tuberculatus e 26 amostras de P. lineata foram obtidas, das quais 29%, 48% e 8% foram positivas respectivamente. Conclui-se que o WSSV está presente em crustáceos e moluscos silvestres, podendo constituir-se como vetores e/ou reservatórios do agente, representando, portanto, um potencial risco a carcinicultura local. É o primeiro relato de WSSV em M. tuberculatus e P. lineata silvestres.

When isolated from the host itself is safe to use, being able to adhere and colonize the intestine. The objective was to isolate probiotic bacteria from intestine of juvenile Litopenaeus vannamei and evaluate the effects of probiotic administration in the performance of cultivated animals experimental challenged infection. Intestinal bacteria were from cultivated shrimp in oligohaline water and saltwalter in dry and rainy seasons, and confronted with Vibrio parahaemolyticus, Vibrio vulnificus, Vibrio alginolyticus and Aeromonas hydrophila. Bacteria showed antimicrobial effect have been identified by molecular biology. Twenty-nine isolates showed antagonistic effect at least one of the tested pathogens. The species that most occurred was Bacillus cereus, the producing of the largest zones of inhibition to the V. alginolyticus and V. vulnificus. The bacterium Citrobacter freundii, from oligohaline water showed the best antimicrobial effect before the four pathogens. The probiotic Bacillus cereus was tested in diet for marine shrimp post-larvae against challenge with V. parahaemolyticus, and V. alginolyticus which evaluated the growth performance of animals, colonization capacity of the probiotic bacteria, pathogens count and histopathological lesions. The use of probiotic had no effect on animals survival, but not for treatments which was used probiotic had a lower weight gain. Animals fed dietary supplementation of probiotic had lower pathogens count those fed without the use. Histopathological lesions were observed in organs and tissues of animals. It can be concluded that it was possible to isolate bacteria having probiotic effect of marine shrimp intestine, wherein the strain Bacillus cereus demonstrated high capacity to colonize the host itself, causing a significant reduction of pathogens. Bactérias com efeito probiótico contribuem para saúde de camarões marinhos em cultivo, em substituição aos antibióticos, exercendo ação antagonista à micro-organismos patogênicos ou por competição por espaço e nutrientes, além de melhorar o apetite levando a um maior crescimento dos animais. Quando isolados do próprio camarão seu uso é seguro, por serem capazes de aderir ou colonizar o intestino destes. Neste sentido, objetivou-se isolar bactérias probióticas do intestino de juvenis de Litopenaeus vannamei e avaliar os efeitos da sua administração sobre o desempenho dos animais cultivados frente infecção experimental. Foram isoladas bactérias do intestino de camarão cultivado em águas oligohalina e salgada, em períodos seco e chuvoso, e confrontadas com Vibrio parahaemolyticus, Vibrio vulnificus, Vibrio alginolyticus e Aeromonas hydrophila, em testes in vitro. As bactérias que produziram efeito antimicrobiano foram identificadas através de biologia molecular.Vinte e nove isolados apresentaram efeito antagônico a pelo menos um dos patógenos testados. A espécie que mais ocorreu foi Bacillus cereus, produzindo os maiores halos de inibição frente ao V. alginolyticus e V. vulnificus. A bactéria Citrobacter freundii, proveniente de água oligohalina apresentou melhor efeito antimicrobiano, perante os quatro patógenos. O probiótico Bacillus cereus foi testado em ração para pós-larvas de L. vannamei, frente a desafio com V. parahaemolyticus, e V. alginolyticus quando avaliou-se o desempenho zootécnico dos animais, a capacidade de colonização das bactérias probióticas, contagem de patógenos e lesões histopatológicas. O uso do probiótico não influenciou nas taxas de sobrevivência dos animais, porém nos tratamentos em que não se utilizou probiótico houve menor ganho de peso. Os animais que receberam ração suplementada de probiótico, tiveram contagem de patógenos inferior aqueles alimentados sem o uso. Não foram observadas lesões histopatológicas nos órgãos e tecidos dos animais. Concluiu-se que é possível isolar bactérias com efeito probiótico do intestino do camarão marinho, sendo que a cepa de Bacillus cereus demonstrou maior capacidade de colonizar o próprio hospedeiro, diminuindo os patógenos.

Among them, atherosclerosis which is a chronic inflammatory disease that leads to changes in the arterial wall. In the present study, were investigated vascular diseases in fish, in the point of view of pathological anatomy. Thus, were evaluated morphologically vascular changes in tissues collected from beijupirá farmed in offshore in Pernambuco. Cardiac tissue samples were collected and submitted to histopathology and transmission electron microscopy (TEM) for the presence of alterations, with subsequent identification of vascular lesions suggestive of atherosclerosis. The histological slides were stained with hematoxylin-eosin (HE), blue alcian, periodic acid of Schiffh (PAS) and reticulin of Gomori. In the morphometric analysis 158 arteries were evaluated, and the images were analyzed with the aid of software. The data concerning to the proportion of the lumen area compared to the area of the media tunic were analyzed according to the Beta regression models for rates and proportions. Arterial lesions were observed throughout the farmed period, especially in the vascular wall, with hyperplasia of intima and media tunic, formation of atheromatous plaque, infiltration of foam cells and signs of luminal stenosis. By means of TEM, were observed changes in the structure of coronary, with thickening of endothelium and basement membrane, proliferation of fibroblasts and collagen fibers, with accumulation of lipid material subendothelial, cell debris adhered in the basement membrane and presence of pinocytotics vesicles with isolated lysosomes. It was found that fish of the specie Rachycentron canadum farmed in captivity develop arterial lesion of chronic inflammatory degenerative type, and also it was found that the increase in weight gain contributes to the reduction of the lumen area, leading to arterial obstruction. Atualmente existe um crescente interesse no desenvolvimento de projetos visando à implantação do cultivo de beijupirá (Rachycentron canadum), necessitando ampliar os conhecimentos acerca das necessidades nutricionais, ciclo reprodutivo e hábito da espécie, principalmente se considerar que estes fatores podem desencadear o aparecimento de doenças, inclusive por patologias circulatórias. Dentre estas, destaca-se a aterosclerose, uma doença inflamatória crônica que conduz a alterações na parede arterial. No presente trabalho, foram pesquisadas doenças vasculares no peixe, sob o ponto de vista da anatomia patológica. Sendo assim, foram avaliadas morfologicamente alterações vasculares em tecidos coletados de beijupirá provenientes de cultivo offshore em Pernambuco. Amostras de tecido cardíaco foram coletadas e submetidas à histopatologia e microscopia eletrônica de transmissão (MET), para averiguar a presença de alterações, com posterior identificação de lesões vasculares sugestivas de aterosclerose. As lâminas histológicas foram coradas por hematoxilina-eosina (HE), alcian blue, ácido periódico de Schiffh (PAS) e reticulina de Gomori. Na análise morfométrica 158 vasos arteriais foram avaliados, sendo as imagens analisadas com auxílio de um software. Os dados referentes à proporção da área do lúmen em relação à área da túnica média foram analisados de acordo com os modelos de regressão Beta para taxas e proporções. Foram observadas lesões arteriais em todo período de cultivo, principalmente na parede vascular, com hiperplasia de túnica íntima e média, formação de placa ateromatosa, infiltração de células espumosas e sinais de estenose luminal. Por meio da MET foram observadas alterações na estrutura das coronárias, com espessamento do endotélio e membrana basal, proliferação de fibroblastos e fibras colágenas, com acúmulo de material lipídico subendotelial, resíduos celulares aderidos à membrana basal e vesículas pinocitóticas com presença de lisossomos isolados. Foi constatado que os peixes da espécie Rachycentron canadum criados em cativeiro desenvolvem lesão arterial do tipo crônica degenerativa inflamatória e que o aumento no ganho de peso contribui para a redução da área do lúmen, levando a obstrução arterial, possivelmente com envolvimento de fatores nutricionais no surgimento das lesões.

An early clinical approach is necessary so that therapy can be effective, provide a better quality of life and increase survival time. Faced with a high incidence rate, our objective was to characterize the clinical, laboratory, cytological and histopathological aspects of mammary tumors in bitches without predilection for a specific breed, age or size. Thirty-six bitches were studied, between August 2010 and March 2011. Medical history was obtained, and the dogs underwent physical examinations for a clinical classification of the cancer (TNMc); blood was collected for hemogram and biochemistry analysis; thoracic radiographs and abdominal ultrasound were performed; citology samples were collected with fine needle aspiration (CAAF) and histopathology samples collected after mastectomy for characterization of tumor type. These data were evaluated by filling out a clinical follow-up sheet for mammary tumors. All animals underwent mastectomy as treatment. Analysis of the sample showed a predominance of subjects with ages 6-10 years (55.5%), normal score (83.3%) with a mixed diet intake (55.5%). The majority (55.5%) of the bitches were nulliparous, with pseudocyesis (25%), tumors in inguinal glands (75%), in both sides of the midline, with multicentric nodules (77.8%), with a prevalence of nodules (27%) larger than 2cm in diameter, classified as carcinomas on citology, while on histopathology there was a higher prevalence of complex carcinomas (30.55%), showing severe anaplasia, anisokaryosis and anisocytosis. Com o aumento da expectativa de vida dos cães, os tumores da mama tem se tornado uma patologia cada vez mais frequente na Medicina Veterinária e se faz necessário uma abordagem clínica precoce para que a terapêutica seja eficaz e proporcione melhor qualidade de vida e prolongamento do tempo de sobrevida. Diante da alta incidência, esta pesquisa teve como objetivo caracterizar clínica, laboratorial, citológica e histopatologicamente os tumores da mama de cadelas sem predileção de raça, idade, e porte. Foram estudadas 36 cadelas, no período de agosto de 2010 a março de 2011, e submetidas à anamnese, exame físico para a classificação clínica do câncer (TNMc), coleta de sangue para hemograma e bioquímico, exames radiográficos do tórax e ultra-sonográficos do abdômen, amostra citológica da lesão por citologia aspirativa por agulha fina (CAAF) e amostra histopatológica coletada após a mastectomia para caracterização do tipo de tumor,. Esses dados foram avaliados através do preenchimento de uma ficha clínica de acompanhamento de tumores da mama. Todos os animais tiveram como tratamento a mastectomia. A amostra foi analisada com predominância de idade 6-10 anos (55,5%), escore normal (83,3%) com ingestão de dieta mista (55,5%). A maioria (55,5%) das cadelas eram nulíparas, apresentando pseudogestação (25%), tumoração das mamas inguinais (75%), em ambas as cadeias, com nódulos multicêntricos (77,8%), prevalecendo nódulos (27%) de tamanho superior a 2cm de diâmetro, na citologia todos foram classificados como carcinoma, enquanto que no histopatológico prevaleceu o carcinoma complexo (30,55%), apresentando intensa anaplasia, anisocariose e anisocitose.

The investigation of viruses Infectious myonecrosis (IMNV), and Infectious Hipodermal and Hematopoietic Necrosis (IHHNV) and White Spot Syndrome (WSSV) was performed by macroscopic analysis, using wet mount, microscopically for histopathology, and analysis molecular (Polymerase Chain Reaction - PCR and nested PCR), identifying the presence or absence of etiological agents. Viruses causing IHHNV IMNV and were detected as lesions suggestive of these infections were more frequent during the dry season. WSS virus was not detected by nested PCR in the specimens, as well as injuries that just allowed the suspected virus circulation during the study period. Lesions suggestive of bacterial diseases, enteritis hemocitical, as well as the presence of protozoa and epicomensais gregarines were observed in the shrimp examined. Infectious diseases affecting the shrimp are complex events and the continuous and accurate records of the farms are essential for epidemiological studies. These, identifying risk factors and involving them in the analysis are essential to maintain and monitor the health of animals and for the good productivity of crops. Camarões cultivados podem ser acometidos tanto por enfermidades não infecciosas, causadas por agentes abióticos, quanto por enfermidades infecciosas, sendo dentre essas as de etiologia viral as responsáveis pelas maiores perdas na carcinicultura. Camarões pequenos e médios foram coletados de quatro fazendas comerciais no litoral do estado de Pernambuco, nos períodos chuvoso e de estio, com o objetivo de investigar a frequência de enfermidades nesses animais. A investigação das viroses Mionecrose Infecciosa Viral (IMNV), Necrose Hematopoiética e Hipodermal Infecciosa (IHHNV) e a Síndrome da Mancha Branca (WSSV) foi realizada pela análise macroscópica, por meio de exame a fresco, microscopicamente, por meio da histopatologia, e por análises moleculares (Reação em Cadeia da Polimerase – PCR e nested PCR), identificando a presença ou não dos agentes etiológicos. HHNV e IMNV foram detectados, assim como lesões sugestivas dessas viroses foram mais frequentes no período de estio. O WSSV não foi detectado por nested PCR nos espécimes. Também não foram verificadas lesões que permitissem a suspeita da circulação deste vírus no período do estudo.Lesões sugestivas de bacterioses, enterite hemocítica, assim como presença de protozoários epicomensais e gregarinas foram constatados nos camarões analisados. Enfermidades infecciosas que acometem camarões cultivados são eventos complexos e registros exatos e contínuos das fazendas são indispensáveis para os estudos epidemiológicos. Esses, identificando fatores de risco e associando-os nas análises são fundamentais para manter e monitorar a saúde dos animais e para a boa produtividade dos cultivos.

Due to the short production cycle and the clinical or subclinical character in many of the diseases that affect pigs, there was the possibility of using the slaughterhouse as an important source of epidemiological data on the incidence and prevalence of disease in flocks, making the monitoring of animals in slaughter houses one of the most important sources of information to obtain data to assess the health situation of production systems for pigs with the aim of obtaining statistics on incidence or prevalence of limiting diseases affecting pigs. Thus, this work was developed to analyze the association between the frequency of infection with helminths and coccidia and property characteristics, and evaluate lesions in organs of pigs in slaughterhouses of the metropolitan area of Recife and of the (“Zona da Mata”) of Pernambuco, Brazil. The work was done in three slaughterhouses of the inspection system state, located in the metropolitan area of Recife and in the (“Zona da Mata”) of Pernambuco state, from July 2008 to May 2009. A total of 715 pigs were analyzed, from eight industrial farms and three of subsistence. The count of eggs / oocysts in the feces was calculated and larval culture for diagnosis of infection by gastrointestinal parasites in fecal samples was performed. Inspection of the viscera for examination of lesions and collection of material for histopathological examination were carried out. A questionnaire was used to ascertain the situation of the farms. The positivity for helminths was 2.7%(12/447), predominantly Strongyloidea type eggs. The presence ofoocysts was detected in 6.5% (29/447),including Eimeria spp and Isospora suis. The gross lesions predominated in lung with 43.8% (313/715), followed by 4.7% (35/715) for liver and kidneys with 2.6% (19/715), with higher frequencies respectively for pneumonia, milk spots and hydronephrosis. Histopathologically, granulomatous pneumonia predominated; in the livers with milk spots it was observed sinusoidal congestion, granulomatous inflammatory foci, peri-granulomatous hepatitis, and eosinophilic infiltration in the interlobular spaces, and in kidney, chronic interstitial nephritis.

Tilapia (Oerochromis niloticus) of cultivations of the state of Pernambuco they were appraised with objective of determining the frequency of bacterial diseases. For so much, samples of several farms were analyzed, in the several aspects, with relevance for the bacterial agents. The tilapia were examined with relationship to the streptococcus presence, víbrios, coliform, pseudomonas and aeromonas. Clinical exams and autopsy were accomplished, for microscopic analysis of the lesions and better definition of the probable agent etiological. The analyses were accomplished at the Laboratory of Sanity of Aquatic Animals (LASAq) of the Rural Federal University of Pernambuco (UFRPE) and in the Center of Development and Diffusion of Technology in Aquaculture of the State University of Bahia (UNEB). The principal pathological agents were víbrios and aeromonas, that are pathogens responsible opportunists for significant losses, being identified the following species in 46 isolated: V. natriegens (1/46), V. metschnikovii (2/46), V. halioticoli (1/46), V. fischeri (2/46), V. mimicus (23/46), V. diabolicus (1/46), V. furnissi (1/46), V. cholerae o1 (1/46), V. scophthalmi (4/46), V. proteolyticus (3/46), V. argarivorans (1/46), V. ordalii (2/46) and Vibrio spp. ( 3/46). The isolated vibrios presented larger sensibility to the antimicrobianos enrofloxacina (100%) and florfenicol (98,18%) and in decreasing order, gentamicina (90,91%), cotrimoxazol (sulfametoxazol+trimetroprim) (76,36%), tetraciclin (67,27%), eritromicin (30,91%) and amoxilina (3,64%). The isolated ones tested they came 100% resistant the penicillin. In this study, 96,4% (53/55) of the víbrios they presented index multiple resistance to antibiotics (MAR), superior to 0,22, characterizing multiple resistance. In 35 isolated the identified aeromonas were: A.caviae (1/35), A. shubertii (11/35), A. media (4/35), A. popoffii (1/35), A. sobria (3/35), A. encheleia (4/35), A. veronii (4/35) e A. jandaei (4/35) Forty were tested isolated of aeromonas with relationship to the sensibility to 08 antimicrobial, of these they showed larger sensibility the florfenicol (100,0%), enrofloxacina(95,0%), gentamicina (95,0%) and in decreasing order, cotrimoxazol (sulfametoxazol+trimetroprima) (67,5%), tetraciclina (65,0%). There was smaller sensibility the eritromicina (20,0%), penicillin (5,0%) and the amoxilina (2,5%), confirming the resistance existence. The index of multiple resistance to antibiotics (MAR) for the isolated of aeromonas it varied in an interval from 0,12 to 0,62, of these 95% (38/40) they came superior to 0,22 characterizing multiple resistance. Most of the species of isolated víbrios is not considered pathogenic for the fish (environmental), but nevertheless they can represent risk for the health of the tilapia for subject of opportunism and of the consumer, mainly if consumed raw. The isolated and identified movable aeromonas in this study are commonly considered as environmental, however many of the analyzed fish presented compatible symptomatology with the illness caused by these agents opportunists. No Brasil, estima-se que a produção anual de tilápias supere 100 mil toneladas, principalmente devido ao potencial produtivo da região Nordeste que em 2004 respondeu por 41 % da produção total de 70.000 toneladas, gerando renda de US$ 200.000.000,00, decorrente de suas condições climáticas, disponibilidade de tecnologia e mercado de consumo, regional e nacional em expansão. A intensificação de cultivos tem como conseqüência o aumento de matéria orgânica, que favorece a multiplicação de microrganismos, possibilitando o surto de doenças na ocorrência de situações adversas aos peixes. Tilápias (Oerochromis niloticus) de cultivos do estado de Pernambuco foram avaliadas com objetivo de determinar a freqüência de doenças bacterianas. Para tanto, analisaram-se amostras de diversas fazendas, nos diversos aspectos, com relevância para os agentes bacterianos. As tilápias foram examinadas quanto à presença de estreptococos, víbrios, coliformes, pseudomonas e aeromonas. Foram realizados exames clínicos e necropsias, para análise microscópica das lesões e melhor definição do provável agente etiológico. As análises foram realizadas no Laboratório de Sanidade de Animais Aquáticos (LASAq) da Universidade Federal Rural de Pernambuco (UFRPE) e no Centro de Desenvolvimento e Difusão de Tecnologia em Aqüicultura da Universidade Estadual da Bahia (UNEB). Os principais agentes patológicos foram víbrios e aeromonas, que são patógenos oportunistas responsáveis por perdas significantes, sendo identificadas as seguintes espécies em 46 isolados: Vibrio natriegens (1/46), V. metschnikovii (2/46), V. halioticoli (1/46), V. fischeri (2/46), V. mimicus (23/46), V. diabolicus (1/46), V. furnissi (1/46), V. cholerae O1 (1/46), V. scophthalmi (4/46), V. proteolyticus (3/46), V. argarivorans (1/46), V. ordalii (2/46) e Vibrio spp.(3/46). Os vibrios isolados apresentaram maior sensibilidade aos antimicrobianos enrofloxacina (100%) e florfenicol (98,18%) e em ordem decrescente, gentamicina (90,91%), cotrimoxazol (sulfametoxazol+trimetroprima) (76,36%), tetraciclina (67,27%), eritromicina (30,91%) e amoxilina (3,64%). Os isolados testados apresentaram-se 100% resistentes a penicilina. Neste estudo, 96,4% (53/55) dos víbrios apresentaram índice múltipla resistência a antibióticos (MAR), superior a 0,22, caracterizando múltipla resistência. Em 35 isolados as aeromonas identificadas foram: Aeromonas caviae (1/35), A. shubertii (11/35), A. media (4/35), A. popoffii (1/35), A. sobria (3/35), A. encheleia (4/35), A. veronii (4/35) e A. jandaei (4/35). Foram testados 40 isolados de aeromonas quanto à sensibilidade a oito antimicrobianos, tendo mostrado maior sensibilidade a florfenicol (100,0%), enrofloxacina(95,0%), gentamicina (95,0%), cotrimoxazol (sulfametoxazol+trimetroprima) (67,5%), tetraciclina (65,0%). Houve menor sensibilidade a eritromicina (20,0%), penicilina (5,0%) e a amoxilina (2,5%), confirmando a existência de resistência. O índice MAR para os isolados de aeromonas variou de 0,12 a 0,62, dos quais 95% (38/40) apresentaram índices superiores a 0,22, caracterizando multiresistência. A maioria das espécies de víbrios isoladas não é considerada patogênica para os peixes (ambientais), mas ainda assim podem representar risco para a saúde das tilápias por questão de oportunismo e do consumidor, principalmente se consumido cru. As aeromonas móveis isoladas e identificadas neste estudo são comumente consideradas como ambientais, porém muitos dos peixes analisados apresentaram sintomatologia compatível com a enfermidade causada por estes agentes oportunistas.

On top of the losses due to diseases, it's important to mention that some of the vibrio species are zoonotic agents, meaning they can also cause diseases in humans. Given the importance of bacteria of the genus Vibrio to shrimp farming and public health, the aim of this study was to evaluate marine shrimp, correlate the clinical findings with the presence of the vibrio bacteria and identify the isolated species in the water of the ponds of cultivated marine shrimp in Pernambuco. The samples were collected from four coastal farms and the laboratory analysis consisted of the research and identification of the vibrio bacteria in the hepatopancreas and in the water of the tanks, and identification of any alteration by examination of fresh samples. Thiosulphate citrate bile salt agar (TCBS) was used as the culture media and the selected colonies were later biochemically tested. Four hundred and eighty shrimps were analyzed, of hose 424 (88.33%) showed to have vibrio and one or more alterations. There were identified a total of 903 alterations, the most frequent of muscle tissue (329; 36.43%) and the least frequent of the hepatopancreas tubules (121; 13.40%). When analizing the growth cycle, it was observed the largest number of alterations (503; 55.7%) in the dry season. Taking into account the weight of the shrimps, it was observed 540 (59.8%) alterations when the average weight was 8g. Out of all the analyzed animals, 314 (65.42%) showed to have vibrio, being 38 samples from the ponds water and 605 shrimp isolated. The most abundant species was V. mediterranei, (21.31%), considered an environmental species non pathogenic to shrimp, and the least abundant species were V. campbellii, V. rotiferanus, V. shiloni, V. splendidus, V. tapetis and V. wodanis (0.16 %). A dependency between the alterations found on the exam and the presence of the vibrio was noticed, showing that the aforementioned exam, combined to microbiological analyzes, is an important tool that should be used when monitoring the farms. It was also noticed a great variety of pathogenic and non pathogenic species of vibrio in the studied samples. Such microorganisms could, eventually, be related to shrimp and human infections, which could represent a risk for shrimp farming and public health respectively. A carcinicultura mundial tem enfrentado nos últimos anos vários impactos causados por enfermidades, que contribuíram para a queda dos índices de desenvolvimento na produção de camarão marinho cultivado. Além das perdas causadas devido às enfermidades, ressalta-se que algumas espécies de víbrio são agentes zoonóticos, ou seja, podem causar doenças também em humanos. Dada a importância das bactérias do gênero Vibrio para a carcinicultura e saúde pública, objetivou-se avaliar camarões marinhos, associar os achados clínicos com a presença de bactérias do gênero Vibrio e identificar as espécies isoladas da água dos viveiros e de camarões marinhos (Litopenaeus vannamei) cultivados no litoral do estado de Pernambuco. As amostras foram coletadas em quatro carciniculturas do litoral e as análises laboratoriais compreenderam pesquisa e identificação de bactérias do gênero Víbrio no hepatopâncreas e na água dos viveiros, e identificação de alterações através do exame a fresco. Para o isolamento das espécies foi utilizado o meio de cultivo Ágar Tiossulfato Citrato Sais de Bile Sacarose (TCBS) e as colônias selecionadas foram posteriormente submetidas a provas bioquímicas. Foram analisados no total 480 camarões, destes 424 (88,33%) apresentaram um ou mais tipos de alteração. Foi identificado um total de 903 alterações, sendo a mais freqüente a da musculatura (329; 36,43%) e a menos freqüente a alteração dos túbulos do hepatopâncreas (121; 13,40%). Com relação ao ciclo de cultivo, foi observado o maior número de alterações (503; 55,7%) no período de estio. Levando-se em consideração a média de peso dos camarões verificou-se 540 (59,8%) alterações quando os mesmos estavam com peso médio de 8 g. Do total de animais analisados 314 (65,42%) apresentavam vibrio e uma ou mais alteração no exame a fresco. Foi obtido um total de 643 isolados de Vibrio, sendo 38 de amostras de água dos viveiros e 605 isolados de camarão. A espécie mais abundante foi V. mediterranei (21,31%), considerada espécie ambiental e não patogênica para o camarão, e as espécies de menor predominância foram V. campbellii, V. rotiferianus, V. shiloni, V. splendidus, V. tapetis e V. wodanis (0,16%). Foi verificada uma dependência entre as alterações encontradas no exame a fresco e a presença de vibrio, concluindo-se que o referido exame, associado à análise microbiológica é uma importante ferramenta que deve ser utilizada no monitoramento da saúde dos animais. Verificou-se também uma ampla variedade de espécies patogênicas e não patogênicas de víbrio nas amostras estudadas, que podem eventualmente estar relacionados a infecções nos camarões e nos humanos, representando um risco para a carcinicultura e para a saúde pública respectivamente.

It was determined the horses´ body composition, physiological (heart and respiratory rate – FC/FR) and metabolic parameters [packed cell volume (HT), total plasma protein (PPT), albumin (ALB), glucose (GLU), lactate (LAC), urea (UR), creatinin (CN), creatine kinase (CK), aspartate aminotransferase (AST), alanine aminotransferase (ALT), total cholesterol (COLT), HDL cholesterol (COLHDL), triglycerides (TRG) in five times: pre-test (fasted), immediately after (T0), 15 (T15), 30 (T30) and 240 minutes (T240) after exercise finish. Lactate was determined in T0, T15 and T30. Results showed these horses had 13,4%± of fat. There were differences (P0,05). It was observed differences in FC, FR, HT and LAC between four beat gait “picada” and four beat gait “batida” (P0,05) ao final da simulação, demonstrando modificações em parâmetros fisiológicos, nas variáveis bioquímicas associados ao metabolismo energético (FC, FR, GLU e LAC) e nos fluídos corporais (HT e PPT) com hemoconcentração. A simulação assemelhou-se a um exercício de média intensidade e média duração, com baixa produção de lactato e significante consumo de glucose. A simulação não foi capaz de modificar as concentrações de alguns lipídeos sanguíneos (COLT, COLHDL e TRG), dos compostos associados ao metabolismo proteíco (ALB, UR, CN) e das enzimas associadas ao metabolismo muscular (CK, AST, ALT). A marcha picada é energeticamente mais dispendiosa que a marcha batida, o que poderá promover implicações práticas nos programas de treinamento e arraçoamento desses dois grupos de animais.

Considering the above objective of this work: to evaluate the effectiveness of the anticoagulant sodium citrate (10%) in blood tests, to check the influence of cooling on the total count of hemocytes (CTH), haematological data correlate with the presence of Vibrio in the hemolymph, to identify the influence of age and seasonality in the total count of haemocytes in shrimp Litopenaeus vannamei. The species were caught shrimp Litopenaeus vannamei from two nurseries of land (A and B) of mariculture Santa Cruz, located in the city of Goiana-PE. The collections are made weekly, for two cycles of cultivation (dry season and rainy season). It is the examination fresh (macro and microscopic) in all animals sampled. The total counts of hemocytes (cells/mm3) were performed immediately after collection and after five hours of chilling in a Neubauer chamber. Immediately after the counting, the samples intended for bacteriological analysis were transported in temperature to the laboratory of health of aquatic animals (LASAq), Universidade Federal Rural de Pernambuco. The data concerning the influence of cooling on the hemocytes were analyzed using the techniques of mathematical modeling (P

One of the threats to the growth of this activity is the occurrence of diseases that affect the cultured animals, and hence, one of the actions taken to prevent or treat sick animals, the use of antibiotics, such as oxytetracycline (OTC). High Performance Liquid Chromatography (HPLC) with Detection Array of Diodes (DAD) was used to evaluate the OTC’s levels in shrimps cultured in tanks and treated with the drug. After the end of the treatment of shrimps with medicated feed containing OTC at 0,2; 0,4 and 0,5 mg/kg for 14 days, the elimination of antibiotic in muscle and the carapace of the animals until 22 days after medication was evaluated. It was verified through the results that the validated method intended to use and the OTC depletion was greater in carapace of animals (from 10 to 13 days) when compared to the muscle (five days). There was no statistical difference (P 0,05) between treatments used for levels of OTC in muscle and carapace. It is essential to point out the importance of quality control of drugs used in aquaculture as well as the deficient review of national and international standards about the use in the analyses of the shrimp whole, and not just the muscle, to evaluate the accordance of OTC residue in sample of crustaceans. O camarão marinho Litopenaeus vannamei é a espécie que mais se destaca na carcinicultura brasileira. Uma das ameaças ao crescimento desta atividade em todo o mundo é a incidência de enfermidades que afetam os animais cultivados, sendo por isso, uma das possíveis ações adotadas para prevenir ou tratar animais enfermos é o uso de antibióticos, como a oxitetraciclina (OTC). Sendo assim, a partir de uma metodologia validada baseada na técnica de cromatografia líquida de alta eficiência (CLAE) com detecção por arranjo de diodos (DAD), avaliaram-se os níveis de oxitetraciclina em camarões cultivados em tanques e alimentados com ração adicionada do antibiótico objetivando-se avaliar a metodologia. Após o término do tratamento dos camarões com OTC nas concentrações de 0,2; 0,4 e 0,5 mg/Kg de ração durante 14 dias foi avaliada a concentração deste antibiótico no músculo e na carapaça dos animais até 22 dias após suspensão da medicação. Verificou-se que o método validado atende ao uso pretendido e foi observado maior tempo de residência da droga na carapaça dos animais cultivados em experimento (de 10 a 13 dias) quando comparado ao do músculo (cinco dias). Não houve diferença estatística (P 0,05) entre os tratamentos utilizados em relação aos níveis de OTC no músculo e na carapaça. É importante ressaltar a importância de um maior controle da qualidade dos fármacos utilizados na aquicultura, assim como, a falta de revisão de normas nacionais e internacionais quanto à utilização nas análises do camarão inteiro, e não somente do músculo, para avaliação da conformidade de crustáceos quanto ao resíduo de OTC.

Specimes of Brycon microleps (piraputanga) captured both from the captivity and from the river on region were studied microbiologically about the mesophiles, total and termtolerants coliforms, Aeromonas and Salmonella, on rain season, and dry season. About specimes were collected liver and encephalo, and to the comparation of values were used the test of correlation of Spearman and the Kolmogorov-Smirnov test. It was verified the sazonality effect (month of collection) over the counting of mesophile, termtolerants coliforms and Aeromonas, at both fish obtained from captivity and river. Higer contamination were observed in finish of dry season and all dry season, then, at most months hots, between August and March. The isolates were A. hydrophila and A. caviae from captivity fishes and A. sobria and A. hydrophila from river fishes, and a relationship was observed between the Aeromonas total number and the coliforms level, in other words, as higher the level of coliforms in sample, higher they were the Aeromonas spp. countings, being the high countings and the low or null, verified in the same months. Salmonella spp. was isolated at one river sample and one of captivity sample. Escherichia coli was isolated in both the fishes, of indicative that some way the water of the two atmospheres was polluted with feces. It was verified that the probability of contamination by mesophiles occurrence in river collected fish is the same as captivity ones (P≥0,05). A bacia do rio Cuiabá no estado de Mato Grosso é uma das principais receptoras de esgotos domésticos e industriais e por isto, os peixes nela capturados podem estar contaminados e representar perigo ao consumidor, sendo a criação de peixes em cativeiro uma alternativa para a obtenção de peixes microbiologicamente melhor. Exemplares de Brycon microleps (piraputanga) oriundos do rio Cuiabá e de cultivo na região foram analisados quanto à bactérias mesófilas, coliformes, Aeromonas e Salmonella, nos meses de chuva e seca. Dos exemplares foram utilizados fígado e encéfalo, e para a comparação dos dados utilizou-se a correlação de Spearman e o teste de Kolmogorov-Smirnov. Verificou-se o efeito da sazonalidade (mês de coleta) sobre a contagem de bactérias mesófilas, coliformes termotolerantes e Aeromonas, tanto em peixes capturados no rio como nos cultivados, sendo as maiores contagens observadas no final do período seco e no início do período chuvoso, ou seja, nos meses mais quentes do ano, entre agosto e março. Foram isoladas A. hydrophila e A. caviae dos peixes de viveiro e A. sobria e A. hydrophila dos peixes do rio e observou-se uma relação entre a contagem de Aeromonas e coliformes, ou seja, quanto maior a contagem de coliformes da amostra maiores foram as contagens de Aeromonas. A Salmonella spp. foi isolada de uma amostra de rio e uma de viveiro. Escherichia coli foi isolada nos peixes de rio e de viveiro, indicando que a água dos ambientes estava contaminada com fezes. Verificou-se que a probabilidade de ocorrência da contaminação por mesófilos em peixes capturados no rio, é a mesma nos obtidos em cultivo (P≥0,05).

At the mammals medicine these values are great known, but on the shrimp culture there still be too much to clear up about haemolynph. Several studies have been realized aiming determines the different kinds of cells and their respective functions. However, the important information like the normal values of the hemocytes total counting (HTC) in different development phases to the Litopenaeus vannamei species and the existence of hemocytes behavior variations on males and females, as well as its relation to anatomo-histopatologic alterations, still being unknown. In face of the exposed, it was aimed to verify the hemocytes behavior on the different cultivated L. vannamei shrimp development phases, the sexual quantitative variation existence, the sodium citrate and Ethylenediaminetetraacetic acid (EDTA) efficacy as anticoagulant, beyond its relation to the detected alterations at the fresh and histopathology exams. 20 samples of haemolynph were collected weekly, being ten (five males and five females) using the sodium citrate anticoagulant and ten using the EDTA anticoagulant. The collects were realized in two aquariums (A and B), on summer and winter times at a commercial shrimp culture located in Goiana/Pernambuco estate. 0,1mL of haemolynph on a proportion of 1:1 (anticoagulant with 10%concentration:haemolynph) were collected from each shrimp to clinical pathology analyses. The hemocyties/mm3counting was realized immediately after the collect and after a five hours interval. The results were statistically analyzed using multiple linear moulds (P

Serum samples were collected from 290 animals, from which 123 were sheep and 167 goats, in 12 properties, to search antibodies anti-Chlamydophila spp, using Complement Fixation micro technique, and from 262 animals, being 167 goats and 95 sheep to search antibodies anti-Toxoplasma gondii, using Indirect Imunofluorescent Antibody technique. Questionnaires were applied to owners to identify risk factors associated to infections. Samples of 23 goats and sheep aborted fetus, stillborn and newborn were used to investigate causes of abortion. Tissues were processed for histopathology and PCR examination. Frequency of animals serum-reagents for Chlamydophila spp was 10,3%, with 12.0% for goats and 8.1% for sheep, It was identified 11/12 (91.6%) focus of infection. All flocks had animals serum-reagents for T. gondii, and frequency of positives was 31.7% for goats and 16.9% for sheep. Risk factors associated to Chlamydophila spp infection for goats were breed (OR=9,10), intensive handling (OR=6,41), the milk exploration (OR=3,19) and natural breeding (OR=3,77). Risk factors associated to T. gondii infection for goats were intensive handling (OR=2,40), milk exploration (OR=2,10), animals originating from other states (OR=7,89) and natural breeding (OR=5,69). The most frequent anatomic and histopathologic findings in fetus were presence of serohaemorhagic fluid in thoracic cavity in 17 (73.91%) fetus, subcutaneous edema in 10 (43.48%) fetus, serohaemorhagic fluid in abdominal cavity in 7 (30.43%), in pericardial sac in 9 (39.13%) and subcutaneous hemorrhage in 8 (34.78%) animal ones; vascular endothelium reaction was seen in lungs, heart, liver, kidney, spleen and brain in nine (39.13%) fetus. Five fetuses (21.74%) had presented compatible injuries with toxoplasmosis as mummification (4/5) and focus of necrosis in placenta and brain (1/5). Search for Chlamydophila spp DNA in fetal tissues was negative for all the samples. One concludes that infections for T. gondii and Chlamydophila spp is widely spread in goat and sheep flocks studied and that Toxoplasma gondii is involved as cause of abortions in these species. Sanitary measures must be adopted to control risk factors identified in this study. Objetivou-se com este estudo investigar a participação da Chlamydophila spp e do Toxoplasma gondii em falhas reprodutivas e identificar os fatores de risco associados à infecção por estes agentes em caprinos e ovinos nas regiões do Litoral/ Zona da Mata e Agreste do Estado de Pernambuco. Foram colhidas 290 amostras de soros, sendo 123 ovinos e 167 caprinos em 12 propriedades para pesquisa de anticorpos anti-Chlamydophila spp, utilizando-se a microtécnica de Fixação do Complemento e de 262 animais, sendo 167 caprinos e 95 ovinos para pesquisa de anticorpos anti–Toxoplasma gondii, utilizando-se a técnica da Imunofluorescência Indireta. Para identificar os fatores de risco associados às infecções foram aplicados questionários junto aos proprietários. Para o estudo das causas de aborto em fetos caprinos e ovinos foram utilizadas 23 amostras de órgãos de fetos, natimortos e neonatos que foram processadas utilizando-se a histopatologia e PCR. A freqüência de animais soro-reagentes para Chlamydophila spp foi de 10,3%, sendo 12,0% para caprinos e 8,1% para ovinos, identificando-se 11/12 (91,6%) focos de infecção. Em 100% das propriedades havia animais soro-reagentes para T. gondii, observando-se 31,7% e 16,9% de caprinos e ovinos positivos, respectivamente. Os fatores de risco associados à infecção por Chlamydophila spp em caprinos foram a raça (OR=9,10), o manejo intensivo (OR=6,41), a exploração leiteira (OR=3,19) e a monta natural (OR=3,77). Os fatores de risco associados à infecção por T. gondii para a espécie caprina foram o manejo intensivo (OR=2,40), exploração leiteira (OR=2,10), animais procedentes de outros estados (OR=7,89) e monta natural (OR=5,69).O achados anátomo-histopatológicos mais freqüentes nos fetos foram: presença de líquido serosanguinolento na cavidade torácica em 17 (73,91%) fetos, edema subcutâneo em 10 (43,48%) fetos, presença de líquido serosangüinolento na cavidade abdominal em 7 (30,43%), no saco pericárdico em (39,13%) e hemorragia subcutânea em 8 (34,78%) animais; reação do endotélio vascular foi observada no pulmão, coração, fígado, rim, baço e cérebro em nove (39,13%) fetos. Cinco fetos (21,74%) apresentaram lesões compatíveis com toxoplasmose como mumificação (4/5) e focos de necrose na placenta e encéfalo (1/5). A pesquisa do DNA da Chlamydophila spp nos tecidos fetais foi negativo para todas as amostras. Conclui-se que as infecções pelo T. gondii e Chlamydophila spp encontram-se disseminadas nos rebanhos de caprinos e ovinos estudados e que o Toxoplasma gondii está envolvido como causa de abortos nessas espécies. Medidas de sanitárias devem ser adotadas para controlar os fatores de risco identificados neste estudo.

These last ones can cause innumerable damages to the shrimp farmers in the whole world. Amongst these diseases, it can be distinguished the Infectious Hypodermal and Hema-topoietic Necrosis (IHHN), with viral etiology, that can be characterized by not causing great mortality, but body deformities. In addition to this, it frequently leads shrimp to heterogenic growth. For viruses diagnosis histology is an efficient tool, allowing the verification of the health of these crustaceans. This study aimed the observation of the occurrence of IHHN characteristic histopatologic injuries in Litopenaeus vannamei, and its relation with parameters of culture of marine shrimp farms in the state of Per-nambuco. After multiple regression statistic analysis it could be concluded that the tem-perature of the water of the pound and its oxygen availability are narrowly related with the occurrence of those histopatologic injuries. Ao mesmo tempo em que crescem os cultivos comerciais de camarão, observa-se o aumento da incidência de enfermidades que podem causar inúmeros prejuízos aos carcinicultores em todo o mundo. Dentre essas enfermidades, destaca-se a Infecção Hi-podermal e Necrose Hematopoiética (IHHN), de etiologia viral que, embora não cause grandes taxas de mortalidade, produz retardo no desenvolvimento e deformidades nos camarões. Para o diagnóstico dessa virose a histologia tem sido uma ferramenta bastante eficiente e que permite maior monitoramento da sanidade desses crustáceos. Desta for-ma, objetivou-se estudar a IHHN em Litopenaeus vannamei relacionando lesões histo-patológicas características e sua relação com variáveis de cultivo. Com base em regres-sões múltiplas conclui-se que existe uma alta relação entre as variáveis de cultivo tem-peratura e oxigênio e a ocorrência destas lesões.

Having the objective to verify occurrence and evolution of the IMNV in Litopenaeus vannamei cultured on the coast of Pernambuco, Brazil, histopathological examination in 60 samples of shrimps from four farms in two cycles of aquaculture was proceeded. The histopatological findings had been correlated the data of the wet mount and the inquiry. Suggestive injuries of IMNV (coagulation necrosis, muscular hemocitic infiltration, spheroid of the ectopic lynphoid organ) were found in samples of the four studied farms with bigger occurrences in the first cycle. However, in the rainy period it had reduction of the occurrence, being associated the handling change. The raise time and the density were variables which influenced significantly (P

In any aquatic species, the transition from life in a wild environment to aquaculture systems is usually followed by several changes, such as culture densities, frequent degradation of environmental quality, mixing of populations of different origin and manipulations, etc. These facts increase the probability of outbreaks of serious diseases. Several virus diseases have occurred, threatening the sustainability of shrimp industry worldwide. Taura virus is considered one of the most harmful pathogens in the Americas, with cumulative mortality between 40 and 95%. Another virus, named Infectious Myonecrosis Virus (IMNV) was first identified in Litopenaeus vannamei reared in Northern Brazil and it is pointed as one of the main causes of the crash in shrimp production in 2004. The objective of this study was to investigate the prevalence of TSV and IMNV by Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) in Pernambuco state, in order to provide important information for the construction of a biosecurity plan. Eleven commercial farms, located in six different cities of the north and south coast, were randomly sampled betweenAugust and December of 2004. Among the 530 animals analyzed, none were vírus positive for Taura, suggesting that the prevalence of this pathogen is lower than 0,06%, even with recent outbreaks in nearby countries. The IMN virus prevalence lied between 0 and 35,56% among the farms, which is considered alarming and requires monitoring mechanisms at the national level. These results constitute the first survey of these shrimp virus carried out in the Americas using a total randomized sample. A carcinicultura cresceu rapidamente em todo o mundo e hoje constitui uma grande indústria, proporcionando emprego para milhares de trabalhadores e milhões em receita. Como toda atividade de aqüicultura, a passagem do ambiente selvagem para o cativeiro, é acompanhada de mudanças, que propiciam o surgimento de doenças. Surtos de diversas doenças foram reconhecidos como uma ameaça a sustentabilidade da indústria do camarão, e alguns deles causaram sérias perdas econômicas para os produtores de vários países. O vírus da Síndrome de Taura é considerado um dos mais perigosos, com mortalidade cumulativa de 60 a 90%, sendo responsável por grandes prejuízos na América Latina. O vírus da mionecrose infecciosa - IMNV (Infectious Myonecrosis Virus), ainda não registrado em outros países, foi identificado no Nordeste brasileiro e apontado como uma das causas para a diminuição da produção nacional em 2004. O objetivo deste trabalho foi investigar a ocorrência dos vírus Taura e IMN, a partir do diagnóstico molecular de Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR), no estado de Pernambuco a fim de subsidiar informações importantes para a construção de um plano de biosseguridade. Onze fazendas pertencentes a seis municípios diferentes, localizados no litoral norte e sul do Estado dePernambuco, foram amostradas aleatoriamente no período de agosto a dezembro de 2004. Dos 530 camarões analisados, nenhum apresentou diagnóstico positivo para o TSV, o que significa que a prevalência deste patógeno no estado de Pernambuco é inferior a uma prevalência mínima por fazenda de 0.06%, mesmo diante dos surtos recentes em países próximos. Em nove das onze fazendas analisadas foram encontrados casos positivos para o IMNV. O vírus IMN apresentou uma prevalência que variou de 0,00% a 35,56%, por fazenda, o que é considerado preocupante, e desperta a necessidade de um monitoramento emnível nacional. Este resultado constitui o primeiro levantamento de vírus de camarão realizado no país, conduzido em uma amostragem não dirigida.

All the goats were male, with no specific race (NSR), and about one year old. Vegetal specimens were brought from the town of Venturosa, Recife and Passira, in after phytochemical analysis, plant from different sites showed similarities and were positive to indicant, glycosis and also had traces of condensed proanthocyanidins. There was neither manifestations of clinical signs not the ocorrence of any death due to the plant ingestion. A greenish coloration was observed the urinalysis; as well as the increase in density (>1040); discrete presence of protein, blood and bilirubin. By the sedimentoscopy, leucocidin, haematuria, besides the presence of renal, urethral cells, cylinders and calcium and phosphate crystals were verified. By the erythroanalysis discrete microcitic anemia, was exhibited. necroscopy alterations consisted of ascites and discrete renal paleness. Histopathological examination the liver, had swelling tumefaction, and vacuolization of hepatocytes, necrotic areas, dissociation of hepatic cords and destruction of sinusoids, areas of congestion and sinusoidal congestion. In the kidneys, there was tubular lesion, degeneration and necrosis of tubular epithelium, glomerulosclerosis, and reactivity of vascular endothelium. The spleen showed discrete hemossiderosis and testicles had testicular degeneration. The leguminosae Indigofera suffruticosa was hepatotoxic, nephrotoxic and caused testicular degeneration in goat (Capra hircus L., 1758). Realizou-se um estudo experimental sobre a atividade de Indigofera suffruticosa Mill (Fabaceae), administrando doses de 10, 20, 30, e 40g/kg/p.v., sob a forma de extrato aquoso a quatro caprinos (Capra hircus L.) e 10g/kg/p.v. da planta in natura”ao quinto animal. Todos os caprinos eram machos, sem raça definida, com cerca de um ano de idade. Os espécimes vegetais utilizados foram provenientes dos municípios de Venturosa, Recife e Passira, após análise fitoquímica, demonstraram semelhança sendo positiva a presença de indican, glicose e traços de proantocianidinas condensadas. Não houve manifestação de sinais clínicos ou ocorrência de óbito pela ingestão da planta. À urinálise, observou-se coloração esverdeada; aumento da densidade (>1040); presença discreta de proteína, sangue, e bilirrubina. Na sedimentoscopia, verificou-se principalmente, leucocitúria. No eritrograma pôde-se constatar anemia microcítica, ainda que discreta. As alterações necroscópicas consistiram de ascite, e discreta palidez renal. O exame histopatológico revelou as seguintes alterações: no fígado, tumefação e vacuolização de hepatócitos, necrose focal, dissociação de cordões hepáticos e congestão e destruição de sinusóides. Nos rins houve, degeneração e necrose do epitélio tubular, glomeruloesclerose e reatividade do endotélio vascular. No baço, discreta hemossiderose e nos testículos, degeneração. A leguminosa Indigofera suffruticosa foi hepatotóxica, nefrotóxica e causou degeneração testicular em caprinos (Capra hircus L., 1758).
