ABSTRACT
In the process of the epidemiological supervision of 4 maternity hospitals in Tyumen 453 Pseudomonas strains, classified with 9 species, were isolated and studied. The overwhelming majority of the strains isolated from nursing articles and medical equipment were classified with P. aeruginosa (86.75 +/- 1.68%) and P. putida (7.11 +/- 1.27%). In the structure of Pseudomonas isolated from humans these species constituted 51.11 +/- 7.45% and 26.67 +/- 6.69% respectively. High occurrence of Pseudomonas contamination of nursing articles and medical equipment in postnatal wards (11.48 +/- 0.82%) and in infants wards (6.92 +/- 0.58%) was established. Sinks of wash-stands (3.76 +/- 1.3-28.5 +/- 2.15%), compressors for the reanimation of infants (11.1 +/- 10.47%), faucets (1.69 +/- 0.7-5.29 +/- 0.92%), etc. were found to be the most contaminated objects which could be the factor of Pseudomonas transmission. The inclusion of bacteriological control into the system of epidemiological supervision in maternity hospitals facilitates the timely detection of unfavorable epidemiological situation and makes it possible to take the necessary measures with a view to decrease the functioning of mechanisms of Pseudomonas transmission well in advance.
