A numerical taxonomic study was carried out with 45 strains of Vibrio and related genera including reference strains to examine whether oxidase negative V. proteus is a biotype of V. cholerae or an independent species, whether the group F organisms belong to Aeromonas or form a separate genus, the exact taxonomic positions of certain culture collection strains assigned to the genus Vibrio, whether the definition of the family Vibrionaceae needs to be modified in the light of the results of the study and the characters required for differentiation of the important genera and species of the family. On the basis of the study, it is recommended that V. proteus having 82% similarity with V. cholerae should be a distinct species of the genus Vibrio, group F strains having 75% similarity with V. cholerae and 72% with Aeromonas should form a separate genus of the family Vibrionaceae, the 2 NCTC strains labeled as Vibrio spp. having 88% similarity belong to V. cholerae the NCTC strains V. alcaligenes be excluded from the family Vibrionaceae, as it is non-fermentative and the definition of the family Vibrionaceae needs amendment to include oxidase negative but otherwise very similar organisms.
