Resumo: The study analyzed 33 specimens of Satanoperca pappaterra, captured from the upper Paraná river floodplain between March 2004 and June of 2005, and 33 specimens of Crenicichla niederleinii captured from the Itaipu Reservoir between November 2005 and November 2006. Both were parasitized by monogeneans pertaining to the genus Sciadicleithrum and by metacercariae of Ascocotyle sp. The relative condition factor (Kn) did not differ significantly between parasitized and unparasitized individuals from the two host species. Only Sciadicleithrum sp.1, parasite of S. pappaterra, presented positive and significant correlation between the relative condition factor (Kn) and the abundance of parasitism. On the other hand, Ascocotyle sp. in both hosts and Sciadicleithrum sp.2 parasite of C. niederleinii did not present correlations between the Kn and the abundance of parasitism.

Ambos estavam parasitados por monogenéticos, pertencentes ao gênero Sciadicleithrum e por metacercárias de Ascocotyle sp. O fator de condição relativo (Kn) não diferiu significativamente entre indivíduos parasitados e não-parasitados das duas espécies de hospedeiros. Apenas Sciadicleithrum sp.1 parasito de S. pappaterra apresentou correlação positiva e significativa entre o fator de condição relativo (Kn) e a abundância de parasitismo. Por outro lado, Ascocotyle sp. de ambos os hospedeiros e Sciadicleithrum sp.2 parasito de C. niederleinii não apresentaram correlações entre o Kn e a abundância de parasitismo.Universidade Estadual De Maringá2008-05-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/362510.4025/actascibiolsci.v30i2.3625Acta Scientiarum.
