It is well known that the unabsorbed O-antisera of Vibrio parahaemolyticus contains considerably high agglutination titer against heterologous O-antigens. To prepare specific O-antisera by eliminating these agglutinins, the mutual relationships of O-antigens of V. parahaemolyticus and the relationships between these O-antigens and the heat-killed cells of other vibrios such as Vibrio cholerae and Vibrio alginolyticus were investigated.
The results were as follows.
1. The V. parahaemolyticus possessed one O-antigen which was non-type specific and common to all strains of V. parahaemolyticus besides the confirmed antigens of 0-1 to 0-12.
2. This common O-antigen of V. parahaemolyticus was also found in V. cholerae and V. alginolyticus but not in Escherichia coli. It seems likely that this O-antigen is distributed among vibrios as a common antigen specific for the genus Vibrio.
