Serological typing of Pseudomonas aeruginosa--comparison of various antigenic schema.

Serotyping sera for both the agglutination (using IMSUT sera) and slide agglutination (using TIBS sera) were succesfully prepared using Homma's serotype strains. They were proved to be type specific and distinct. The two typing sera (IMSUT and TIBS) were used to determine the correspondence of major O-antigens among the different kinds of serotype schema which are used at present throughout the world. The serotype sera of Lanyi, Liu and Meitert were also used for the same purpose. The relationships among serotypes of the seven schemata were clarified as shown in tables in the text. Cross-reactions were found among several serotypes in each of several serotype schemata was suggested.
