| Abstract: | To find out if the transfer of P. aeruginosa infection by droplet route is possible in resuscitation and intensive care units, the bacteriological study of air samples taken in different rooms of resuscitation units (altogether 234 air samples) was carried out with the subsequent identification and typing of isolated P. aeruginosa strains. In most cases (70.5%) the microbial contamination of the air in the main rooms of resuscitation units was found not to exceed 500 microbial cells per cu. m, and no P. aeruginosa strains were isolated. The identification and typing of six P. aeruginosa strains isolated from the air of an isolation ward for patients with infectious complications made it possible to find out intraspecific differences of these microorganisms, as all of them belonged to strains of different sero- and pyocinotypes. Thus, the results of these investigations indicate that the droplet route of the transfer of P. aeruginosa hospital infection is not characteristic of resuscitation and intensive care units, as no P. aeruginosa strains are isolated from the main rooms of such units; likewise, no circulation of this microorganism was observed in the air of an isolation ward for patients with infectious complications. |
