Diversity of parasites of fish from the Upper Paraná River floodplain, Brazil.
TLDR
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

TLDR
The condition factor for nine species of tropical freshwater fish in the upper Paraná River floodplain is described and knowledge of the nine species is important for adequate management and maintenance of the biological equilibrium of the ecosystem. Expand
Influence of host sex and age on infracommunities of metazoan parasites of Prochilodus lineatus (Valenciennes, 1836) (Prochilodontidae) of the upper Paraná River floodplain, Brazil.
TLDR
Only Tereancistrum curimba showed significant difference in the prevalence between the sexes, with females being more parasitized, and Amplexibranchius sp. Expand
Parasite-host relationship between the tambaqui (Colossoma macropomum Cuvier 1818) and ectoparasites, collected from fish farms in the city of Rolim de Moura, State of Rondônia, Western Amazon, Brazil
TLDR
Despite 100% prevalence, the high water quality contributes to infracommunities with low parasite abundance and good levels of Kn, HSR and SSR, allowing good tambaqui development. Expand
Host population density as the major determinant of endoparasite species richness in floodplain fishes of the upper Paraná River, Brazil.
TLDR
It is suggested that in the floodplain of the upper Paraná River (with homogeneous physical characteristics and occurrence of many flood pulses), population density of different host species might be the major determinant of their parasite species richness. Expand
Giant african snail, Achatina fulica (Férussac, 1821): an environmental and public health problem in the northwestern of Paraná State, Brazil
TLDR
The results showed that most of the respondents know the snail and are concerned about the transmission of diseases and losses in agricultural crops, but few recognize this pest as the basis of environmental imbalance. Expand
New species of Tereancistrum Kritsky, Thatcher & Kayton, 1980 (Monogenea: Dactylogyridae: Ancyrocephalinae) from the gills of Prochilodus lineatus (Osteichthyes: Prochilodontidae) from the upper
Two new species of Tereancistrum Kritsky, Thatcher & Kayton, 1980 are described from the gills of Prochilodus lineatus (Prochilodontidae) collected from the upper Paraná River floodplain, Brazil. T.Expand
Parasitism influence on the hepato, splenosomatic and weight/length relation and relative condition factor of Prochilodus lineatus (Valenciennes, 1836) (Prochilodontidae) of the Upper Paraná River
One hundred and forty-nine specimens of Prochilodus lineatus (Valenciennes, 1836) were collected on the Upper Paraná River floodplain (Brazil) from February 2000 to June 2001. Both parasitized andExpand
Influence of the seasonal and environmental patterns and host reproduction on the metazoan parasites of Prochilodus lineatus
One hundred and forty-eight specimens of Prochilodus lineatus (Valenciennes, 1836) were collected on the Upper Parana River floodplain, Brazil. Kritskyia boegeri presented significant differences inExpand
Infective pentastomid larvae from Pygocentrus nattereri Kner (Pisces, Characidae) from the Miranda River, Pantanal, Mato Grosso do Sul State, Brazil, with notes on their taxonomy and epidemiology.
TLDR
During parasitological surveys of freshwater fish from the Miranda River, Brazil, 199 Pygocentrus nattereri Kner (Characidae) was caught and represents a new intermediate host record for the genera Alofia, Leiperia and Subtriquetra. Expand
