S. B. aMetazoan parasite communities of wild Leporinus friderici (CharaciformesbAnostomidae) from Amazon River system in Brazil.h[electronic resource] c2017 aThis study compared the structure of metazoan parasite communities in two populations of Leporinus friderici from two rivers of the Amazon River system in Brazil. Jainus leporini, Urocleidoides paradoxus, Urocleidoides sp., Tereancistrum parvus, Tereancistrum sp., Clinostomum marginatum, Procamallanus (Spirocamallanus) inopinatus, Contracaecum sp., Octospiniferoides incognita and Ergasilus sp. were found in both hosts. There were differences in species richness of parasites, Shannon index and the evenness between both host populations, because the parasite community showed a similarity of only 33%. Parasites of both host populations had an aggregated dispersion. Host size also contributes to the differences between the populations of hosts investigated, and the feeding habit contributes to the occurrence of endoparasites in L. friderici, an intermediate host for these parasites. The existence of variation in infracommunity and community of parasites for the same host species from different localities indicates the presence of an uneven distribution in terms of species and density of parasites, which are intermediate hosts, and some of them constitute food items for L. friderici in the localities surveyed. aEcology aFreshwater fish aInfection aEcologia aInfecção aParasito de animal aPeixe de água doce aAmazon aAnimal parasite1 aGONÇALVES, R.
