  ABSTRACT: A total of 879 Staphylococcus aureus clinical isolates from 17 medical institutions in different regions of Russia were tested. Susceptibility to 18 antimicrobials was determined by agar dilution in accordance with the NCCLS recommendations. The most potent antimicrobials were glycopeptides, linezolid, and fusidic acid, to which no resistance was found. Other antimicrobials with low frequency of non-susceptibility were mupirocin (0.3%), trimethoprim/sulfamethoxazole (0.8%), quinupristin/dalfopristin (1.8%) and rifampicin (7.0%). Fluoroquinolones displayed moderate activity (5.8% of non-susceptible strains to moxifloxacin, 9.1% to levofloxacin, 13.1% to ciprofloxacin). High rates of non-susceptibility were found to clindamycin (27.1%), gentamicin (30.7%), tetracycline (37.1%), erythromycin (39.6%) and chloramphenicol (43.1%). The prevalence of oxacillin-resistant S. aureus (ORSA) was 33.5% and varied from 0% to 89.5% in different hospitals. ORSA were isolated most frequently in the burn units (77.5%), intensive care units (54.8%), trauma and orthopedics units (42.1%). This is the first multicenter study published of antimicrobial resistance of S. aureus in Russia which meets international standards.

  ABSTRACT: Prevalence of Klebsiella pneumoniae among gramnegative pathogens of nosocomial infections in intensive care units of 33 hospitals of 22 towns in Russia was investigated. Antibiotic susceptibility and extended-spectrum beta-lactamase production were tested in 420 nosocomial K. pneumoniae isolates. Carbapenems (imipenem, meropenem and ertapenem) showed the highest activity. Extended-spectrum beta-lactamase production based on the phenotyping methods was revealed in 342 (81.4%) isolates. The maximum activity against the K. pneumoniae isolates producing extended-spectrum beta-lactamase was observed in imipenem and meropenem (no unsusceptible strains were isolated). 3.2% of the isolates was not susceptible to ertapenem. Differences in the activity of cefoperazone/sulbactam, amikacin, ciprofloxacin and levofloxacin against the extended-spectrum beta-lactamase producing isolates in various hospitals were recorded.
