Abstract: Trypanosome infections have been reported in several species of fish, in majority of cases described on the basis of morphological characteristics. Trypanosomes in fish are heteroxenous and transmitted by hirudineans. This study aims to evaluate the prevalence and density of infections by Trypanosoma sp. in blood from three species of catfish, Hypostomus regani, H. strigaticeps, H. albopunctatus, from the Mogi Guacu River, Pirassununga, Sao Paulo, Brazil. Further, this study intends to characterize the Trypanosoma specimens found in the blood of these fish by morphological and molecular techniques. The trypanosomes overall prevalence observed was 47.6% with a general average density of 0.75 parasites/mu l of blood. Hypostomus regani and Hypostomus strigaticeps showed a significant difference in prevalence. The average densities of parasites were not significantly different among the three fish species. Similar findings were observed for the monthly variations in densities. The parasites found in the three species of catfish studied showed similar morphological characteristics. The morphological data and the statistical analyses used in this study didn't show the formation of groups. The analyses provided evidence of the presence of pleomorphisms in the trypanosomes found in the three studied fish.

metadata.dc.description.abstractalternative: Infecções por tripanossomas foram descritas em diversas espécies de peixes, sendo a maioria das descrições baseada nas características morfológicas. Tripanossomas de peixes são heteroxenos e transmitidos por hirudíneos. Este estudo tem como objetivo a avaliação da prevalência e densidade da infecção por Trypanosoma sp. no sangue de três espécies de cascudos, Hypostomus regani, H.strigaticeps, H.albopunctatus, do Rio Mogi-Guaçu, Pirassununga, São Paulo, Brasil. Além disso, pretende-se a caracterização das espécies de Trypanosoma encontradas no sangue desses peixes, por meio da utilização de técnicas morfólogicas e moleculares. A prevalência total de tripanossomas foi de 47,6%, e a densidade média foi de 0,75 parasitas/ µl de sangue. Hypostomus regani e Hypostomus strigaticeps apresentaram diferenças significativas em prevalência. As médias das densidades dos parasitas não apresentaram diferenças significativas entre as três espécies de peixes estudadas. O mesmo foi observado com a variação mensal das densidades. Os parasitas encontrados nas três espécies de cascudo possuíam características morfológicas semelhantes. As análises morfológicas e estatísticas obtidas neste estudo não mostraram a formação de grupos. As análises evidenciaram a presença de pleomorfismo dos tripanossomas encontrados nas três espécies de peixes estudados.
