The nature of Kanagawa phenomenon KH of Vibrio parahaemolyticus was studied, and it was found that KH is an expression of strong hemolytic activity in media containing high concentration of NaCl, in which hemolytic factor diffused into media rapidly. Fermentable carbohydrates played an important role for the production of Kh in media containing 7 NaCl, with different KH patterns by different carbohydrates. The promotion of growth by breakdown products of carbohydrates and lowered pH were supposed to influence the production of KH factor. In the study on survival of V. parahaemolyticus at various temperatures in seawater and 3 NaCl, this organism was found to grow at 37C and 20C. This organism showed a slow growth in 3 NaCl but not in sea water at 10C or below. The survival time of this organism was 150 to 200 days in 3 NaCl at 37C to 10C, but was short and variable in sea water.
