[Extraction and characteristics of agglutinating sera to the O-antigens of Pseudomonas aeruginosa].

A method of preparation of antigens of Verder and Evans and a scheme of rabbit immunization suggested by them was used to obtain agglutinating specific O-sera to 12 type Ps. aeruginosa strains of Bulgarian and London collections. There was shown a principal correlation of the O-types of Ps. aeruginosa cultures of both collections. A possibility of using the sera obtained for typing the Ps. aeruginosa on glass was confirmed. Of 80 museum cultures 52 strains were typed; among them type 0-6 was frequently encountered.
