Serological relationships among the strains of pathogenic Vibrio isolated from cultured eels and between the eel isolates and the species of the genus Vibrio were studied by means of Ouchterlony immunodiffusion techniques and agglutinin adsorption tests with rabbit antisera prepared against representative strains of the present isolates. The present eel isolates were antigenetically very homologous : All representative five isolates produced four lines of identity in Ouchterlony plates, and possessed agglutinins (flagellar and at least one heat-stable antigens) in common. The species of the genus Vibrio exhibited slight relationships to the eel isolate : V. anguillarum strains, V. parahaemolyticus strain, and V. alginolyticus strain shared one precipitin band with the present eel isolate, and V. anguillarum strains, V. fischeri strains, V. parahaemolyticus strain, and V. alginolyticus strain had agglutinins, most likely flagella antigen, common to the present eel isolate. These results well agree with those of the previous DNA studies, and present another piece of evidence supporting that the present eel isolate is a new member of the genus Vibrio.
