Seventy-four Vibrio strains were isolated from imported frozen seafoods and identified according to their physiological and biochemical properties. They included two V. cholerae non-0l sp., two V. diazotrophicus sp., one V. hollisae sp., five V. natriegens sp., eight V. fluvialis sp., and four V. nereis sp. Two of them were not identified as Vibrio species. When these strains were tested using API-20E ket for identification, however, only the results for two V. cholerae and five of the V. fluvialis strains matched the results obtained previously. Due to the importance of detecting V. cholerae from foods, phylogenetic identification of the strains was attempted based on restriction fragment length polymorphism (RFLP) of the 16S rDNAs amplified by PCR. The results suggested that the two strains had identical RFLP patterns which were more closely related to that of V. proteolyticus than V. cholerae. The problems associated with identification of pathogens originated from seafoods demand development of accurate and rapid identification methods.
