A total of 297 strains of Vibrio fluvialis and Vibrio furnissii, which were collected from various countries for the past 15-year period of 1984-1998, were serogrouped. Of those examined, 239 strains of V.fluvialis and V.furnissii were classified into 29 known O serogroups; 9 strains were found to belong to R-form cultures, and the rest of the 49 strains could not be serogrouped. Of those serologically untypable strains, 26 novel O serogroups (O36 to O61) were established and added to our reference of the V.fluvialis and V.furnissii antigenic scheme. As all antisera against the O reference strains of the organisms contained some amount of antibody to the rough (R) antigen, all diagnostic O antisera were absorbed with the reference rough strain, V.fluvialis GF25.
