Various studies have been carried out on the morphological, physiological, biochemical and serological characteristics of V. parahaemolyticus, an enteropathogenic halophilic bacteria, which is known to contain various types of hemolysins, one of which produces hemolysis known as the Kanagawa phenomenon. With the discovery of this phenomenon, a problem arose concerning the pathogenicity of V. parahaemolyticus and the epidemiology of food poisoning. This study was made to clarify questions on the Kanagawa positive and negative strains, and was divided into taxonomical and genetic research and research concerning enteritis producing power. Findings suggest that a enterotoxic substance may be produced by all strains of V. parahaemolyticus, and that Kanagawa-negative vibrios may possess potential enteropathogenicity.
