Evidence for the presence of a K antigen in strains of Vibrio anguillarum

ElevenVibrio anguillarum O group 1 strains, isolated from different species of diseased fish, were selected for an immunoelectrophoretic study. Antigenic preparations for immunoelectrophoresis were simple water extracts boiled for 1 h. Using O and OK antisera, immunoelectrophoretic patterns suggested the presence of a K antigen; there is evidence that examined strains possess a common K antigen.
