Aeromonas salmonicida is the causative organism of fish furunculosis, a serious communicable disease affecting primarily Salmonidae and notifiable under the United Kingdom Diseases of Fish Act, 1937. Unfortunately, because of similar pathologies it is impossible to differentiate unequivocally by clinical signs alone between furunculosis and other fish diseases caused by Gram-negative bacteria. In practice, however, a provisional diagnosis is made and treatment started, confirmation being delayed until sufficient growth for identification (usually 3 to 4 days) of the isolate has occurred on primary culture-media. Although a recently introduced method (McCarthy & Rawle, 1975) has reduced this delay to24 by permitting serological identification of both scanty and impure growths of A. salmonicida, a requirement for rapid diagnosis still exists, both because furunculosis is a notifiable disease and because the increasing drug resistance of A. salmonicida makes specific therapy essential.
