Diversity of parasites of fish from the Upper Paraná River floodplain, Brazil.
Monogeneans presented the highest number of species, followed by digeneans, and the infection site with the highest species richness was the intestine, with 127 species. Expand
Checklist of Crustacea parasitizing fishes from Brazil
The fauna of parasitic crustaceans of Brazilian fishes is the richest in the region when comparing these data with those recorded for the fishes from other parasite hotspots of Neotropics (Mexico and Caribbean). Expand
Endoparasite infracommunities of Hemisorubim platyrhynchos (Valenciennes, 1840) (Pisces: Pimelodidae) of the Baía River, Upper Parana River floodplain, Brazil: specific composition and ecological
Several species of parasites were correlated with host size and sex, and may be explained by increase in food content and possible behavioral modifications of male and female hosts. Expand
Cestodes in South American freshwater teleost fishes: keys to genera and brief description of species
Keys to genera of cestodes in South American freshwater teleost fishes are provided, with diagnoses of genera and short descriptions of species. Two new genera are proposed, Chambriella gen.n. forExpand
Diplostomum (Austrodiplostomum) compactum (Lutz, 1928) (Platyhelminthes, Digenea) metacercariae in fish from the floodplain of the Upper Paraná River, Brazil
Diplostomum (A.) compactum was overdispersed in the population of Hoplias aff. Expand
Ecological aspects of endohelminths parasitizing Cichla monoculus Spix, 1831 (Perciformes: Cichlidae) in the Paraná River near Porto Rico, State of Paraná, Brazil.
Prevalence and total host length were positively correlated in fish parasitized by P. macrophallus and Q. machadoi in males and females of C. monoculus. Expand
Ecological aspects of endoparasite fauna of Acestrorhynchus lacustris (Lütken, 1875) (Characiformes, Acestrorhynchidae) on the Upper Paraná River floodplain, Brazil
There was significant difference in the prevalence and abudance of infection of Q. torquatus between hosts sexes and there was significant positive correlation between the prevalence of Contracaecum Type 1 and host standard length. Expand
Henneguya corruscans n. sp. (Myxozoa, Myxosporea, Myxobolidae), a parasite of Pseudoplatystoma corruscans (Osteichthyes, Pimelodidae) from the Paraná River, Brazil: a morphological and morphometric
This paper describes the parasite Henneguya corruscans n. sp. which infects the gills of Pseudoplatystoma corruscans Spix and Agassiz, 1829 found in the Paraná River, Brazil. The parasites belong toExpand
Aspects of the ecology of proteocephalid cestodes parasites of Sorubim lima (Pimelodidae) of the upper Paraná River, Brazil: I. Structure and influence of host's size and sex.
Between March 1992 and February 1996, 107 specimens of Sorubim lima were collected in the floodplain of the upper Paraná river. Ninety-five (88.78%) specimens were parasitized with at least oneExpand
Ecological aspects of metazoan endoparasites of Metynnis lippincottianus (Cope, 1870) (Characidae) from Upper Paraná River floodplain, Brazil
Results suggest that species are coexisting without competition in Metynnis lippincottianus, Brazil, and positive association between D. pacupeva and two nematode species was observed, including positive and significant covariation between their abundances. Expand
