Susceptibility of 25 clinical isolates of Chlamydia trachomatis to the most commonly used antimicrobials for the treatment of chlamydial infections was studied. Of 25 isolates, 10 were determined as in vitro resistant to doxycycline, 10 – to …

In vitro susceptibility study of nosocomial strains of Pseudomonas aeruginosa isolated from patients with nosocomial infections in 21 Russian ICUs was performed. Antibiotics with antipseudomonal activity, such as piperacillin, …

Objective. To determine in vitro activity of antimicrobials against S. aureus isolated from hospitalized patients from different regions of Russia. Materials and Methods. A total of 879 clinical strains of S. aureus isolated in 2000–2001 from patients hospitalized in 17medical institutions in different parts of Russia. Susceptibility to 18 antimicrobials: oxacillin, vancomycin, teicoplanin, linezolid, erythromycin, clindamycin, lincomycin, gentamicin, mupirocin, fusidic acid, ciprofloxacin, levofloxacin, moxifloxacin, quinupristin/dalfopristin, rifampicin, trimethoprim/sulfamethoxazole, tetracycline, chloramphenicol was determined by agar dilution method in accordance with the NCCLS recommendations.

Objective. To determine the structure of antimicrobial resistance of clinical isolates of pneumococci in different regions of Russia. Materials and Methods. A total of 210 Streptococcus pneumoniae strains isolated in 15 centres of Central (Moscow – 5 centers, Kazan, Nizniy Novgorod, Ryzan), North-Western (Smolensk, Saint-Petersburg), Southern (Krasnodar) regions, Urals (Ekaterinburg) and Siberia (Novosibirsk, Tomsk) were included in this study. Susceptibility to 19 antimicrobials – penicillin G, amoxicillin, amoxicillin/clavulanate, cefotaxime, cefepime, erythromycin, azithromycin, clarithromycin, midecamycin, midecamycin acetate, spiramycin, clindamycin, tetracycline, ciprofloxacin, levolfloxacin, chloramphenicol, co-trimoxazole, rifampicin and vancomycin – was determined by broth microdilution in accordance with NCCLS recommendations.
