| Abstract: | Goussia carpelli was found parasitizing the intestine and gall bladder of Cyprinus carpio, Carassius carassius and Barbus barbus bocagei, and less frequently Leuciscus cephalus cabeda and Chondrostoma polylepis, from the Esla River. The coccidian is described and data on its prevalence, intensity and pathogenicity are given. In histological sections, the oocysts were detected in the lamina propria or submucosa. We did not observe a clear seasonal pattern nor an influence of the host sex on the infections. On the contrary, there was a tendency to a decrease in the prevalence with the age of the host. |
