Abstract

The bacterial disease agents were isolated from aquaculture in Basra govern-orate, Iraq during October 2015 to April 2016. A total of 65 specimens of Cyprinus carpio were infected (47%). Four bacterial diseases were diagnosed by clinical signs that appeared from severe infections of external and internal organs (Fin rot, Dropsy, Bacterial gill disease, and Vibriosis). Bacteria were identified according to their morphological characterization and using Vitek II system and they include: Aeromonas sobria, Aer. hydrophila, Raoultella ornithinolytica, Enterobacter cloacae, Staphylococcus haemolyticus, Staphylococcus lentus, Globicatella sanguinis, and Vibrio cholerae. The results of the present study show that the emergence of diseases in the fish farms is may be linked to the stress factors experienced by the fish, or a possibility of bacteria transition either from water to fish or the opposite or by handling. Raoultella ornithinolytica and Lobicatella sanguinis are the first bacterial isolates to be registered in Basra.
