O objetivo desta pesquisa foi registrar a presença de cestoides Trypanorhyncha, suas prevalências e intensidades de infecção, na musculatura e serosa abdominal parietal de 50 exemplares de Macrodon ancylodon, capturados no litoral Norte do Brasil e beneficiados em Belém, Estado do Pará, durante o período de junho de 2004 a janeiro de 2005. A musculatura e serosa abdominal dos peixes foram examinadas em mesa de inspeção candling table após o filetamento das amostras. Oito peixes encontravam-se parasitados por plerocercoides da espécie Poecilancistrium caryophyllum, com prevalência de 16% e intensidade média de infecção de um plerocerco por peixe, tendo como único sítio de infecção a musculatura. A espécie Poecilancistrium caryophyllum é, pela primeira vez, registrada para M. ancylodon. The aim of this research was to report the presence of Trypanorhyncha cestodes, their prevalence and mean intensity in the muscles musculature and abdominal serose in commercial fish processed in Belém, Pará State. Fifty specimens of M. ancylodon were captured in the North Coast of Brazil. The musculature and adjacent abdominal serose of fish were analized in a "candling table" after filleted. Eight specimens were parasitized by plerocercoids of Poecilancistrium caryophyllum, with a prevalence of 16% and mean intensity of infection of one plerocercus per fish, varying from the unique site of infection was the musculature. The species P. caryophyllum is reported by the first time on M. ancylodon.

O objetivo deste estudo foi determinar as especies de Anisakidae parasitando congro-rosa, Genypterus brasiliensis Regan, 1903 comercializados nos mercados dos municipios de Niterói e Rio de Janeiro, Brasil, de interesse em saúde pública, enfatizando seus índices parasitarios, sitios de infecção e importância higiénico-sanitária. Setenta e quatro espécimes de G. brasiliensis foram necropsiados de outubro de 2002 a setembro de 2003.

From August 2010 to May 2011 was conducted a study about the parasitism in the organs and attached glands of the gastrointestinal system of goats and sheeps reared in the municipalities of Quixad?, Chor?, Banabui?, Quixeramobim, Ibicuitinga, Morada Nova, Jaguaretama, Itapi?na and Ibaretama, representing a sample of the regions of Central Hinterland and Lower Jaguaribe, sent for slaughter in the municipal public slaughterhouse of Quixad?, state of Cear?. Were simultaneously collected biometric data of children between three months and six years old, born and domiciled in the municipalities of Quixad? and Morada Nova, state of Cear?, accompanied by the Family Health Program, which were compared with the scale standards of reference for the Brazilian population. The study was finished at the ninth month because of the interdiction of the establishment in May 2011. It was showed the parasitism by cestodes of the species Taenia hydatigena (larval form), in a variety of sites (liver, omentum, gallbladder and serosas of duodenum, abomasum, pylorus, uterus, colon, bladder and rumen) and by adult form of Moniezia expansa, in small intestine; by nematodes in abomasum and small intestine (Haemonchus contortus, Trichostrongylus colubriformis, T. axei and Cooperia punctata), and in large intestine (Oesophagostomum columbianum, Trichuris globulosa and T. ovis), with the highest prevalence presented by H. contortus. It was confirmed the hypothesis of low-income housing of sheep and goats, and nutritional deficiency in the population of amerindian heritage, with tradition in the consumption of animal protein; there are sub-nutrition and malnutrition, identified by biometrics data, and there are also cases of obesity in significantly fewer than what happens in the Brazilian population of reference. Entre agosto de 2010 e maio de 2011 foi desenvolvido estudo sobre o parasitismo nos ?rg?os e gl?ndulas anexas do sistema gastrintestinal de caprinos e ovinos criados nos Munic?pios de Quixad?, Chor?, Banabui?, Quixeramobim, Ibicuitinga, Morada Nova, Jaguaretama, Itapi?na e Ibaretama, representando amostra das regi?es do Sert?o Central e Baixo Jaguaribe, do Estado do Cear?, encaminhados para abate no Matadouro P?blico Municipal de Quixad?. Simultaneamente foram recolhidos dados biom?tricos de crian?as (idade, peso corporal e altura) com a idade variando entre tr?s meses e seis anos, nascidas e domiciliadas nos Munic?pios de Quixad? e Morada Nova, acompanhadas pelo Programa Sa?de da Fam?lia, que foram analisados e comparados com os das escalas padr?es de refer?ncia para a popula??o brasileira. Foi comprovada a infec??o (parasitismo) por metacest?ides de Taenia hydatigena (forma larvar), em diversos s?tios dos hospedeiros (f?gado, omento, ves?cula biliar e serosas do duodeno, abomaso, piloro, ?tero, intestino grosso, bexiga e rumem) e pela forma adulta de Moniezia expansa, no intestino delgado; por nemat?ides no abomaso e intestino delgado (Haemonchus contortus, Trichostrongylus colubriformis, T. axei e Cooperia punctata), e no intestino grosso (Oesophagostomum columbianum, Trichuris globulosa e T. ovis), sendo a maior preval?ncia para H. contortus. Foram confirmadas as hip?teses de baixo rendimento de carca?a dos ovinos e caprinos, e a defici?ncia nutricional da popula??o de origem amer?ndia, com tradi??o no consumo de prote?na de origem animal; h? sub-nutri??o e desnutri??o, identificadas pelos dados biom?tricos, e tamb?m h? casos de obesidade em n?mero significativamente menor do que acontece na popula??o brasileira de refer?ncia.

Specimens of Prochilodus argenteus (Actynopterygii: Prochilodontidae) were collected in the upper S?o Francisco River, downstream from the Tr?s Marias Dam and downstream of the confluence of the Abaet? River with the San Francisco between 2004 and 2008 during periods of dry and rain. We found 34 species of parasites: adult specimens of Saccocoelioides nanii; Anacanthoroides sp. Apedunculata discoidea; Telethecium sp; Tereancistrum ornatus; Tereancistrum toksonum; Tereancistrum sp.1, sp.2, sp.3 and sp4.; Rhinonastes sp.; Guyanema sp.; Philometra sp.; Philometrioides sp.; Spinitectus asperus; Neoechinorhynchus prochilodorum; Acusicola sp.; Argulus multicolor; Dolops nana; Gamidactylus sp. Placobdella and unidentified copepod sp. and larval specimens of Henneguya sp. Myxobolus franciscoi; Myxobolus sp.1 sp.2; Acanthostomum sp.; Austrodiplostomum sp.; metacestode sp.2 and sp.1; Valipora sp.; Contracaecum sp.; Hysterothylacium sp. and Lernaea sp.. Associations were found between different pairs of species, thus were inferred that the presence of a species favored the presence and increased abundance of others. Among the biotic factors, sex of the hosts did not influence the prevalence, intensity and abundance indexes of ecological infrapopulations or diversity, dominance and evenness, ecological indexes infracommunity. The standard length and body weight showed a weak negative correlation with some indices and ecological communities of hosts smaller and lighter were characterized by greater richness and lower dominance. The relative condition factor and the coefficient of growth when compared with the default values of the collection site showed no changes in infected individuals collected downstream of the dam of Three Marias, but these proved to be decreased in infected fish collected downstream from the confluence of the river San Francisco with the Abaet? River. Hosts from the two locations and collection periods showed different parasitological indexes, and those collected downstream from the Tr?s Marias dam during the dry period were most affected by this phenomenon. It is likely that these differences are linked to differences in the dist composition in different locations and collection periods. Limnological conditions different between the two sites and then modulate the reproduction of P. argenteus and may be relevant factors in determining patterns of parasitism. Additional studies about migration conducted by the populations of P. argenteus are necessary to better understand the parasitism and its variations in this region. Esp?cimes de Prochilodus argenteus (Actynopterygii: Prochilodontidae) foram coletados no alto rio S?o Francisco, ? jusante da barragem de Tr?s Marias e ? jusante da conflu?ncia do rio Abaet? com o rio S?o Francisco entre 2004 e 2008 durante os per?odos de estiagem e chuvoso. Foram encontradas 34 esp?cies de parasitos: esp?cimes adultos de Saccocoelioides nanii; Anacanthoroides sp.; Apedunculata discoidea; Telethecium sp; Tereancistrum ornatus; Tereancistrum toksonum; Tereancistrum sp.1, sp.2, sp.3 e sp4.; Rhinonastes sp.; Guyanema sp.; Philometra sp.; Philometrioides sp.; Spinitectus asperus; Neoechinorhynchus prochilodorum; Acusicola sp.; Argulus multicolor; Dolops nana; Gamidactylus sp.; cop?pode n?o identificado e Placobdella sp. e esp?cimes larvais de Henneguya sp.; Myxobolus franciscoi; Myxobolus sp.1 e sp.2; Acanthostomum sp.; Austrodiplostomum sp.; Metacest?ide sp.1 e sp.2; Valipora sp.; Contracaecum sp.; Hysterothylacium sp.e Lernaea sp.. Foi encontrada associa??o entre diversos pares de esp?cies, assim podemos inferir que a presen?a de uma esp?cie favoreceu a presen?a e o aumento da abund?ncia das demais. Dentre os fatores bi?ticos, o sexo dos hospedeiros n?o influenciou a preval?ncia, a intensidade e a abund?ncia, ?ndices ecol?gicos das infrapopula??es, nem a diversidade, a domin?ncia e a equitabilidade, ?ndices ecol?gicos das infracomunidades. O comprimento padr?o e o peso corporal apresentaram correla??o negativa fraca com alguns dos ?ndices ecol?gicos e as comunidades dos hospedeiros menores e mais leves foram caracterizadas por maior riqueza e menor domin?ncia. O fator de condi??o relativo e o coeficiente de crescimento quando comparados com os valores padr?o da localidade de coleta n?o apresentaram altera??es nos indiv?duos parasitados coletados ? jusante da barragem de Tr?s Marias, mas estes mostraram-se diminu?dos em peixes parasitados coletados ? jusante da conflu?ncia do rio S?o Francisco com o rio Abaet?. Hospedeiros provenientes das duas localidades e per?odos de coleta apresentaram diferentes ?ndices parasit?rios, sendo aqueles coletados ? jusante da barragem de Tr?s Marias durante a estiagem os mais acometidos por este fen?meno. ? prov?vel que estas diferen?as estejam ligadas a diferen?as na composi??o da dieta dos hospedeiros nas diferentes localidades e per?odos de coleta. Condi??es limnol?gicas distintas entre as duas localidades modularam a reprodu??o de P. argenteus e podem ser fatores relevantes na determina??o de padr?es de parasitismo. Estudos complementares a respeito das migra??es realizadas pelas popula??es de P. argenteus s?o necess?rios para que seja poss?vel compreender melhor o parasitismo e suas varia??es nesta regi?o.
