[Immunotyping of freshly isolated strains of Pseudomonas aeruginosa].

During 1972-1982 the bacteriological study of 1391 patients with thermal burns was carried out. As the result of clinico-bacteriological studies, the occurrence of P. aeruginosa was found to increase from 39.3% to 70.5% during this period. The immunotyping of P. aeruginosa cultures isolated in 3 burn-treatment centers showed that strains belonging to immunotypes 2, 3, 7 and 3/7 were most frequently isolated from burn wounds. These strains were found to be the cause of hospital infections in burn-treatment hospitals. In connection with the data thus obtained immunological preparations intended for the prophylaxis and treatment of P. aeruginosa infection should include P. aeruginosa strains, immunotypes 2, 3, 7 and 3/7.
