In this study, we confirmed histopathological changes of the channel catfish,Ictalurus punctatus infected with Ichtyobodo necator (Flagellata,Zoomastigia),Ambiphrya ameiuri(Ciliata,Peritricha),Apiosoma micropteri(Ciliata,Peritricha) and Heteropolaria colisarum (Ciliata,Peritricha).I.necator infected gills causing clubbing of filaments. A.ameiuri attached to the body surface showing a gold dust-appearance and skin degeneration. A.micropteri attached to gills evoking degeneration of respiratory epithelia. H.colisarum invaded the skin forming ulcerative lesions on the body surface including fins.}, pages = {1--9}, title = {Histopathological Studies on Parasitic Protozoan Diseases of the Channel Catfish in the United States}, volume = {13}, year = {1986} }
