Description
In 1982, a bacterial disease occurred among cultured eel at the Fisheries Laboratory, University of Tokyo, in Shizuoka Prefecture.<BR>The typical symptom of this disease was a swollen head. Several fish were killed every day, and the total mortality by this disease was about 50-60%.<BR>The bacteria isolated from the diseased fish were Gram-negative and non-motile. Catalase, cytochrome oxidase, gelatinase, esculin hydrolysis, VP reaction and growth at 37°C were negative. Carbohydrate utilization was fermentative. Citrate utilization and indole production were positive. The organisms showed different reactions at maltose and mannitol utilization, and ONPG test. And one of the organisms (maltose-negative, mannitol-positive, and ONPG test-negative) has the same characteristics of the causative agent from ulcerative disease in goldfish.<BR>The present isolates showed pathogenicity for eel by the intraperitoneal injection.
