Abstract

Some Halophilic organisms during summer season has been shown to have a toxic effect on normal human intestine. This study was designed to investigate the toxicity in vivo and biochemical characteristics of halophilic organisms on food poisoning. Seven strains of salt-loving organisms were isolated from feces obtained from four diarrhea patients in out break of food poisoning which was obviously due to ingestion of sea fish called "mulchi" (Auris thajard) in Korea. Information concerning food poisoning due to vibrio parahaemolyticus and survey about it in Korea is scarce. Nevertheless, such diagnosis of food poisoning diarrhea is used to explain food poisoning due to vibrio parahaemolyticus. In the present experiment biochemical characteristics of isolated strains, their antigenicity, and comparison of properties between strains isolated and strains studied outside this country were studied.
Additionally, the relation of hemolytic phenomena during culture on rabbit blood agar plate and virulence test in rats were evaluated. Six strains of these salt-loving organisms were antigenically not related to k-Type antigen of vibrio parahaemolyticus isolated by Japanese workers, but it was revealed that these strains were antigenically related each other.
Seven strains showed toxicity in mice and six out of seven revealed hemolytic phenomen. The results indicate that antigenicity between experimental strains and strains isolated by Japanese workers was different and biochemical characteristics of experimental strains are accompanied by cellobiose fermention.
