Abstract


The aim of this scientific work consisted in establishing the specific ethiology of gills infection, which has been found on the occasion of regullar clinic and anatomopathological examinations, in some freshwater species of fish originating from the Danubian Delta area. Following these examinations, there has been pointed out the macroscopical lesions of gills together with the presence and morphology of parasitic cysts. The microscopic examination of the cysts resulted in diagnosing the specific pathological agent, which was the metazoan Henneguya psorospermica. These aspects and more are being presented in this paper.
