Nested-PCR ,Pneumocystis sp ,bats - Abstract
Pneumocystis has been isolated from a wide range of unrelated mammalian hosts, including humans, domestic and wild animals. It has been demonstrated that the genome of Pneumocystis of one host differs markedly from that of other hosts. Also, variation in the chromosome and DNA sequence of Pneumocystis within a single host species has been observed. Since information about the occurrence and nature of infections in wild animals is still limited, the objective of this work was to detect the presence of Pneumocystis sp. in lungs of bats from two states from Brazil by Nested-PCR amplification. The bats, captured in caves and in urban areas, were obtained from the Program of Rabies Control of two States in Brazil, Mato Grosso and Rio Grande do Sul, located in the Mid-Western and Southern regions of the country, respectively. DNAs were extracted from 102 lung tissues and screened for Pneumocystis by nested PCR at the mtLSU rRNA gene and small subunit of mitochondrial ribosomal RNA (mtSSU rRNA). Gene amplification was performed using the mtLSU rRNA, the primer set pAZ102H - pAZ102E and pAZ102X - pAZY, and the mtSSU rRNA primer set pAZ102 10FRI - pAZ102 10R-RI and pAZ102 13RI - pAZ102 14RI. The most frequent bats were Tadarida brasiliensis (25), Desmodus rotundus (20), and Nyctinomops laticaudatus (19). Pneumocystis was more prevalent in the species Nyctinomops laticaudatus (26.3% = 5/19), Tadarida brasiliensis (24% = 6/25), and Desmodus rotundus (20% = 4/20). Besides these species, Pneumocystis also was detected in lungs from Molossus molossus (1/11, 9.1%), Artibeus fimbriatus (1/1, 100%), Sturnira lilium (1/3, 33.3%), Myotis levis (2/3, 66.7%)and Diphylla ecaudata (1/2, 50%). PCR products which could indicate the presence of Pneumocystis (21.56%) were identified in DNA samples obtained from 8 out of 16 classified species from both states (5 bats were not identified). This is the first report of detection of Pneumocystis in bats from Brazil. Pneumocystis tem sido isolado de uma grande variedade de hospedeiros mamíferos, incluindo humanos, animais domésticos e selvagens. Tem se demonstrado que o genoma do Pneumocystis de um hospedeiro difere marcadamente do de outros, assim como há variação no cromossomo e na seqüência de DNA dentro de uma única espécie de hospedeiro. Sabendo que a informação da ocorrência e natureza da infecção em animais silvestres ainda é limitada, o objetivo do trabalho foi detectar, por Nested-PCR, a presença de Pneumocystis sp. em pulmões de diferentes espécies de morcegos de dois estados do Brasil. Estes mamíferos voadores foram capturados em cavernas, áreas florestadas, de campo e urbanas pelo Programa de Controle da Raiva do Mato Grosso (região Centro-Oeste) e do Instituto de Pesquisas Veterinárias Desidério Finamor (RS) e Instituto Sauver no Rio Grande do Sul (região Sul). Os DNAs foram extraídos de 102 pulmões e realizado Nested-PCR utilizando os primers pAZ102H-pAZ102E e pAZ102X/R1-pAZY/R1 para amplificação do gene mtLSU-rRNA, e pAZ102 10F-RI - pAZ102 10R-RI e pAZ102 13-RI - pAZ14-RI para amplificação do gene mtSSU-rRNA. As espécies mais freqüentes foram Tadarida brasiliensis (25), Desmodus rotundus (20) e Nyctinomops laticaudatus (19). Pneumocystis foi detectado com maior prevalência nas Nyctinomops laticaudatus (26,3% = 5/19), Tadarida brasiliensis (24% = 6/25) e Desmodus rotundus (20% = 4/20). Além destas espécies, Pneumocystis foi também detectado nos pulmões de Molossus molossus (1/11, 9,1%), Artibeus fimbriatus (1/1, 100%), Sturnira lilium (1/3, 33%), Myotis levis (2/3, 66,7%)e Diphylla ecaudata (1/2, 50%). Os produtos de PCR indicaram a presença de Pneumocystis (21.56%) em amostras obtidas de 8 das 16 espécies classificadas para ambos os estados (cinco morcegos não foram classificados). Este é o primeiro registro de detecção de Pneumocystis em morcegos no Brasil.

O controle de produtos de origem animal está diretamente associado à sanidade animal e à saúde pública. Na suspeita de mastite, tanto bacteriana quanto micótica, o congelamento de amostras de leite permite aumentar o período de tempo para análise microbiológica, permitindo um correto diagnóstico laboratorial. As leveduras são os principais agentes ambientais envolvidos na mastite micótica. O objetivo do presente trabalho foi verificar se o congelamento afeta a recuperação de leveduras potencialmente presentes no leite. Foram utilizados seis isolados: Rhodotorula sp. (L1), Geotrichum sp. (L2), Cryptococcus sp. (L3), Candida tropicalis (L4) e Candida albicans (L5), oriundos de leite in natura, e um isolado de C. parapsilosis (ATCC 22019). Após a inoculação experimental, as amostras foram congeladas durante 10 dias, 3, 6 e 8 semanas. O congelamento do leite por períodos superiores a 10 dias causou redução no número de células viáveis. Sugerimos que sejam utilizados períodos mais curtos de congelamento para a análise micológica do leite. The control of animal products is directly linked to the animal sanity and public health. When suspecting mastitis, either bacterial or mycotic, freezing milk samples increases the period of time for a microbiological analysis, thus allowing a correct laboratorial diagnosis. Yeasts are the main environmental agents involved in mycotic mastitis. The objective of the present work was to verify if freezing affects the recovery of yeasts present in the milk. Six isolates were used: Rhodotorula sp. (L1), Geotrichum sp. (L2), Cryptococcus sp. (L3), Candida tropicalis (L4) and Candida albicans (L5), isolated from milk in natura, and one C. parapsilosis (ATCC 22019) isolate. After experimental inoculation, the samples were frozen during 10 days, 3, 6 and 8 weeks. Milk freezing for periods longer than 10 days caused a reduction in the number of viable cells. We suggest that shorter freezing periods are used for the mycological analysis of milk.

As doenças respiratórias constituem um sério problema em sistemas intensivos de criação de suínos, causando enormes prejuízos à industria suína no Brasil e no mundo. Estes prejuízos estão freqüentemente relacionados à redução de peso, mortalidade, maior predisposição a doenças entéricas, gastos com vacinas e medicamentos. Os distúrbios respiratórios em suínos são manifestados através de um complexo de doenças, com envolvimento de agentes virais, bacterianos e fúngicos. Dentre estes, a presença do circovírus (PCV2) e o Pneumocystis sp. começa a ser gradativamente caracterizada como uma associação entre um agente causador de imunossupressão e um organismo de ação oportunista. O trabalho objetivou diagnosticar Pneumocystis sp. através das técnicas de imunohistoquímica, Grocott e nested-PCR, em suínos abatidos nos Estados do Rio Grande do Sul (RS) e Mato Grosso (MT), diagnosticar a ocorrência de PCV2 na mesma população de suínos, verificar a associação entre Pneumocystis sp. e PCV2, e determinar as relações filogenéticas entre as amostras de Pneumocystis sp. O estudo avaliou um total de 591 pulmões, 297 com alterações macroscópicas (pneumonia) e 294 normais obtidos em frigoríficos. Foram analisados 292 pulmões procedentes do RS e 299 pulmões do MT Para diagnóstico do Pneumocystis sp. as amostras foram analisadas através das técnicas de Grocott, Imunohistoquímica e nested-PCR (mtLSU e mtSSU rRNA). Do total das amostras, 36,9% foram positivas para Pneumocystis. O índice de positividade para o vírus PCV2 foi de 32,7% na amostra total. Os resultados revelaram uma alta prevalência do vírus (PCV2) em pulmões sem lesões macroscópicas. A co-infecção (PCV2 e Pneumocystis sp.), foi detectada em 28,0% em 564 pulmões examinados. As análises das seqüências dos nucleotídeos dos produtos de PCR dos genes mtLSU e mtSSU do rRNA do Pneumocystis sp. nos pulmões analisados, sugerem a presença até o presente momento de 2 espécies diferentes de Pneumocystis no Brasil. Este estudo evidencia a ocorrência da co-infecção de dois agentes (Pneumocystis sp. e PCV2) em animais hígidos, fato que, indica a necessidade de planejamento e implementação de medidas de controle para melhorar a produtividade na suinocultura. Respiratory diseases are a major problem in intensive systems of swine husbandry. They are a cause for high losses in the swine industry in Brazil and in the world. These losses are often related to weight reduction, mortality, higher vulnerability to enteric diseases, and expenses with vaccines and drugs. Respiratory diseases in swine appear through a complex of diseases, caused by virus, bacteria and fungi; among these, the porcine circovirus 2 (PCV2) and Pneumocystis sp., the former an agent which causes immunosupression and the latter an oportunistic microorganism. Both are being recognized as capable of being associated. The objectives of this study were to: identify Pneumocystis sp. through immunohystochemistry techniques, Grocott and nested-PCR in swine slaughtered in the States of Rio Grande do Sul and Mato Grosso (MT); investigate PCV2 in the same swine population; investigate the association between Pneumocystis sp. and PCV2, and establish a filogenetic relationship between isolated of Pneumocystis sp. The study was carried out with a total of 591 lungs, 297 with macroscopic alterations characteristic of pneumonia, and 294 normal lungs from the industry. 292 lungs came from RS and 299 lungs came from MT. In order, to diagnose Pneumocystis infection, samples were analysed through Grocott technique, immunohystochemistry and nested-PCR (mtLSU and mtSSU rRNA). Among all samples 36,9% were positive for Pneumocystis sp.. PCV2 virus was found in 37,2% of the samples. Results revealed a high prevalence of the PCV2 virus in lungs without macroscopic lesions. Co-infection (PCV2 and Pneumocystis sp.) was found in 28,0% of 564 lungs examined. So far, the analyses of the sequences of nucleotides from the products of PCR from the genes mtlSU rRNA and mtSSU rRNA from Pneumocystis obtained from the examined lungs suggest that, it is possible the existence of two different species of Pneumocystis in Brazil. This study shows co-infection by two agents (Pneumocysts sp. and PCV2) in apparently healthy animals. This fact points out the necessity planning and implementation of control measures in order to improve productiviy in swine husbandry and industry.

Background: Wild boar population is present worldwide. Contact between wild boars and domestic pigs may occur occasionally, and several diseases, as well as the occurrence of opportunistic infections are observed in both species. Mycotic rhinitis and pneumonia were reported before in pig herds, mainly associated with immunosuppression caused by viral infection. This study reports the occurrence of mycotic rhinitis in two wild boars due to Aspergillus fumigatus, A. flavus and Candida albicans, together with Pneumocystis sp. in the lungs, originating from a herd infected with PCV2. Cases: In a commercial wild boar herd, poor body condition, sneezing and diarrhea were observed. Three animals were euthanized and, in two of them, yellow and green plaque-like masses of fungal growth in the mucosal and in cartilage surface and accentuated atrophy of nasal turbinates were observed. Additionally, multifocal subcutaneous abscesses in the maxillary area and bilateral reddening of the ocular mucosa with muco-purulent discharge were noted. Microscopically, in fragments from the nasal cavity of the two affected wild pigs, massive ulceration of the mucosal surface and presence of hyphae with septations and dichotomous branching and pseudohyphae were observed. Multifocal moderated interstitial pneumonia and alveolar edema were the main histological lesions founded in the lungs of 3 animals. In the lymph nodes multifocal moderated lymphoid depletion and lymphohistiocytic infiltrated was the main microscopical lesion. Aspergillus fumigatus, A. flavus and Candida albicans were isolated in nasal cavity. Pseudomonas aeruginosa was isolated from the subcutaneous abscesses and Staphylococcus hyicus and Streptococcus equisimilis from ocular swab. Pneumocystis was detected in lungs from the three wild boars by nested PCR, Grocott's staining and immunohistochemistry (IHC). Porcine circovirus 2 (PCV2) was detected in lungs by PCR. Virus detection by IHC was only confirmed in one wild boar. Discussion: Diagnostic of mycotic rhinitis and pneumonia was based on macroscopical and microscopical findings, as well as mycological analysis, IHC and Groccott 's methenamine staining. Pneumocystis carinii, Aspergillus spp. and Candida spp. are considered as opportunistic fungal pathogens commonly associated with immunosuppression in animals and hu- mans and have been found in lungs and in muco-cutaneous tissue of PMWS affected pigs. Clinically, immunodeficiency is usually associated with illness caused by organisms of low pathogenicity or well-know secondary pathogens, among other factors. Besides immunodeficiency, prolonged antimicrobial therapy is another predisposing factor to the develop- ment of mycotic infections, well described in animals. In the present report, antimicrobial therapy was performed when respiratory signs were noted in therapeutic doses, suggesting that massive antibiotic use was not the trigger of mycotic rhinitis. PCV2 IHC result positive only in one wild pig, although all the samples were positive by PCR. This finding could indicate a subclinical infection or a recovery phase of the disease in the IHC negative cases, as previously suggested for domestic and wild pigs using in situ hybridization. PCV2 load in wild boar was lower when compared with domestic pigs. A viral load higher than 108 PCV2 genomes per 500 ng DNA was required to give a visible IHC staining in swine. Although quantitative PCR it was not used in order to detect PCV2 in the present report, the viral load could be another possible explanation for the IHC negative cases observed. The role of PCV2 as a cause of immunosupression, facilitating the infection with secondary agents as Aspergillus, Candida and Pneumocystis cannot be ruled out. [ABSTRACT FROM AUTHOR]

- Abstract
Pneumocystis spp. are fungi that are able to infect a variety of host species and, occasionally, lead to severe pneumonia. Porcine circovirus type 2 (PCV2) is an important viral pathogen which affects both swine and wild boar herds worldwide. Co-infection between PCV2 and other pathogens has been reported, and the secondary immunodeficiency caused by the virus may predispose to these co-infections. In the present study, postmortem tissue samples obtained from wild boar herds in Southern Brazil were analyzed by histopathology, ultra-structural observation, and immunohistochemistry. Forty-seven out of seventy-eight (60%) wild boars showed clinical signs, gross, and histopathological lesions characteristic of infection by PCV2. Pneumocystis was detected by immunohistochemistry in 39 (50%) lungs and viral antigens of PCV2 were found in 29 (37.2%) samples. Concomitant presence of Pneumocystis and PCV2 were observed in 16 (20.5%) of the wild boars. Cystic and trophic forms of Pneumocystis were similar to previously described ultra-structural observations in other mammals. [ABSTRACT FROM AUTHOR]

The veterinary literature registers sporadic cases of infections caused by environmental microorganisms in which the main agents involved are yeasts, yeasts-like and filamentous fungi. In relation to dairy animals, the yeasts are more frequently incriminated as the aetiological agents of mycotic mastitis. Most cases occur under the form of localized outbreaks and / or after treatment with antimicrobial agents. The main genera involved in mastitis are Candida and Cryptococcus, besides others such as Geotrichum, Pichia and Trichosporon. The purpose of this review is to point out the main aspects of mastitis caused by yeasts and yeast-like fungi, such as etiology, predisposing factors, pathogenicity, diagnosis, treatment and prophylaxis, through a chronological approach of the first reports, with main focus on results described recently in national and international veterinary literature. The mycotic mastitis control should be mainly focused on preventive methods, especially based on adequate management of essential factors like proper milking procedures and a high level of hygiene of the environment and equipments, with the aim of reducing the number of affected animals, assuring the quality and innocuity of dairy food safety.
