Characterization of Pseudomonas aeruginosa strains isolated at therapeutic institutions of Moscow

: Investigation of 108 P. aeruginosa strains isolated from various clinical material revealed that 54.63% of them belonged to serogroups 2, 5, 16, 18, 20 and 12.96% to serotype 4. Five strains were polyagglutinated. Monocultures of P. aeruginosa were isolated from 55% of patients, in the majority of cases (31 out of 36) these strains were isolated from the urine. Bacterial associations were more frequently detected in discharge from wounds (11 out of 21), in the material obtained by bronchoscopy (9 out of 15), and in the throat (5 out of 6). Assessment of antibioticograms of the isolated P. aeruginosa strains permitted us characterize polymixin, forte ceftazidime, and biseptol as effective agents.
