Abstract
|
|
|
|
We reported an outbreak of Aeromonas (A.) veronii responsible for ulcerative dermatitis in Israeli carp (Cyprinus carpio). The major clinical signs were darkening body, abdominal extension, exophthalmos and severe ulcerative necrosis in the skin. The necropsy showed yellowish ascites, necrosis in liver and enlargement of kidney and spleen in the morbid fish. In blood agar for culturing bacteria, three different colonies were identified as A. veronii, Plesimonas shigelloides and Shewanella putrefaciens by phylogenetic identification using 16S rRNA or gyrB gene sequences. A. veronii was the most dominant species among them and was resistant to ampicillin, nalidixic acid and oxytetracycline.
