Antimicrobial Resistance

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.

Objective. To determine in vitro activity of fusidic acid and other antimicrobials available for topical use against S. aureus isolated from hospitalised patients. Materials and Methods. A total of 879 clinical strains of S. aureus isolated in 2000-2001 from patients hospitalised in 17 medical institutions in different parts of Russia - 4 in Central region, 2 in North-West region, 3 in South region, 2 in Volga region, 3 in Ural region, 3 in Siberian region, were included in the study.

The rates of nasopharyngeal carriage of Haemophilus influenzae and epidemiology of its antimicrobial resistance in healthy children from day-care centers have been investigated. The overall rate of nasopharyngeal H.influenzae carriage was 44%. The …

β-Lactamases are represented by extensive range of genetically and functionally different enzymes that are able to destroy β-lactams that leads to development of resistance to these antibiotics in β-lactamases producing bacteria. Intrinsic production …
