A search was made for the diagnostic tests for the disease of cultured eels due to the present bacterium.
It is considered impossible to differentiate the disease of eels caused by the present bacterium, by means of external signs of diseased fish, from that caused by other eel pathogens such as Aeromonas hydrophila, Edwardsiella tarda, Vibrio anguillarum, and Pseudomonas anguilliseptica. This necessitates the isolation and identification of the infectious agent for diagnosis.
Positive proof was obtained that the diluted rabbit antisera prepared against representative strains of the present bacterium can be used for diagnostic purpose. In addition, a simplified identification method by the use of API 20E was shown.
It was proposed that the disease of cultured eels caused by the present vibrio be named as vibriosis of eels Type B ; that due to V. anguillarum as Type A.
