1. Community structure of metazoan parasites in Hemibrycon surinamensis (Characidae) from the Matapi River in the State of Amapá, Brazil
Abstract Abstract: The aim of this study was to investigate the community of metazoan parasites in Hemibrycon surinamensis from the Matapi River, State of Amapá, Brazil. Among the 31 examined fish, 77.4 % were parasitized by Jainus hexops, Tereancistrum ornatus (Monogenea), Contracaecum sp. (Nematoda), Clinostomus marginatum and Posthodiplostomum sp. (Digen

2. Helminth parasites of Cichla ocellaris Bloch & Schneider, 1801 collected in the Jacaré-Pepira River, São Paulo state, Brazil
Abstract:Cichla ocellaris is native to the Amazon region. It is popularly known as tucunaré and is widely used for human consumption. It is difficult to breed in captivity due to its highly predatory habits, it is considered symbolic of sport fishing in Brazil. This study aimed to make a qualitative and quantitative survey of helminth parasites of C. ocella

3. Parasitic communities of Hoplosternum littorale (Hancock, 1828) as indicators of environmental impact
ABSTRACT The parasites are indicative of several biological aspects of their hosts, including their diet, migration, recruitment and phylogeny, but they can also be direct indicators of the environmental quality. Hoplosternum littorale is a fish that has a high commercial value in some South American countries. The fishes were collected from January to July

4. Community structure of metazoan parasites of silverside, Odontesthes bonariensis (Pisces, Atherinopsidae) from Argentina
The helminth communities of silverside, Odontesthes bonariensis (Valenciennes, 1835), from two Argentinean lagoons were studied and compared at component community and infracommunity levels. Nine helminth species were found: five digeneans (Austrodiplostomum cf. mordax, Ascocotyle (Phagicola) cf. diminuta, Ascocotyle sp., Thometrema bonariensis and Saccocoel

5. Parasitos metazoários de cetáceos da costa nordeste do Brasil. / Metazoan parasites of cetaceans of the northeast coast of Brazil.
Cetaceans are parasitized by a wide diversity of endo and ectoparasites in various tissues, organs and cavities. Some species are related to causes of strandings and mortality of dolphins and whales. In addition to knowledge about the pathological effects of these organisms, their importance in ecological and evolutionary studies is highlighted. The parasiti

7. Influence of the seasonal and environmental patterns and host reproduction on the metazoan parasites of Prochilodus lineatus
Cento e quarenta e oito espécimes de Prochilodus lineatus (Valenciennes, 1836) foram coletados na planície de inundação do Alto rio de Paraná, Brasil. Kritskyia boegeri apresentou diferenças significativas na abundância de acordo com os estágios de maturação de gonadal do hospedeiro. Ergasilus sp apresentou correlação negativa entre o RGS das fê
