Özet

The bacterium, Citrobacter freundii was isolated from naturally infected aquarium fish species (Poecilia sp., Xiphophorus clemenciare, Xiphophorus pygmaeus, Carassius auratus and Astronotus ocellatus), and its pathogenicity was tested using healthy 1.5-year-old rainbow trout. The infection caused gross clinical symptoms such as ulcerative lesions on skin, distended abdomen, pale liver, darkened spleen, watery kidney, bloody exudate in gastro-intestinal system too. Histopathological abnormalities were observed in tissues of skin, gills, liver, kidney, spleen and intestine. In a therapeutic experiment injection with oxytetracycline controlled the infection.
