[Serotyping strains of Pseudomonas aeruginosa]

A total of 552 strains of Pseudomonas aeruginosa were obtained in 1970-1975 from different hospitals; the strains were isolated from various sources. Serotyping of these cultures was carried out with the aid of a set of agglutinating sera (20 in all) prepared by the author, and 97.5% of these cultures were typed. A high percentage of the strains belonging to the II, III, and IV serological groups and to the serotype 011 pointed to the epidemiological significance of these serological groups. The results obtained showed the expediency of introduction of the method of serological typing of the Ps. aeruginosa cultures into the public health practice for the purpose of epidemiological analysis.
