[Microbiological characterization of pneumonia in patients of intensive care unit].
The aim of study was bacteria characterization, isolated from 30 patients with microbiologically confirmed pneumonia, hospitalized in ICU of Rydygier's Hospital in Krakow. In the study, endotracheal aspirates (ETA) were being collected and quantitatively inoculated. Bacteria isolation at the concentration of > or =10(6) CFU/ml was recognized as bacteriological etiology of pneumonia. Studied 140 clinical materials and isolated 251 bacterial strains from 16 divers species. Isolation of bacteria at the concentration of > or = 10(6) CFU/ml, on the day of clinically recognized HAP, was observed in 26 patients and presence of 1 species of bacteria at the pathological concentration was detected in 17 patients. In the study of endotracheal aspirates, which were collected after 3 and 6 days of treatment, isolation of bacteria species at the significant concentration was observed appropriate in 15 and 10 patients. In the etiology of infections predominated: P. aeruginosa, A. baumannii, S. maltophilia (17 strains; 47.2%) and Enterobacteriaceae bacilli (12 strains; 33%), including bacilli ESBL-positive. The surveillance of bacterial susceptibility patterns detected high percentage of resistance P. aeruginosa strains to imipenem (38.7%).
