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
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
Diversity, specificity and speciation in larval Diplostomidae (Platyhelminthes: Digenea) in the eyes of freshwater fish, as revealed by DNA barcodes.
Larvae (metacercariae) in some species of Diplostomidae (Platyhelminthes: Digenea) inhabit fish eyes and are difficult to identify to species based on morphology. DNA barcoding has clarified theExpand
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
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
Host–parasite interaction between branchiurans (Crustacea: Argulidae) and piranhas (Osteichthyes: Serrasalminae) in the Pantanal wetland of Brazil
It is believed that the higher rates of infestation in the dry season result from the increase in host density in drying ponds imitating the conditions found in fish farming, and seasonal changes in water level and temperature can also influence the rates of parasitism. 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
Helminthes and protozoan of farmed pirarucu (Arapaima gigas) in eastern Amazon and host-parasite relationship
This study is the first to record the occurrence of P. macrorhynchus in A. gigas farmed in Amazon, and the number of I. multifiliis was positively correlated with the weight and total length of hosts, while the intensity of monogenoideans was negatively correlated with body weight andtotal length.
