antimicrobial resistance

Species of the family Enterobacteriaceae represent the most prevalent group of nosocomial pathogens. In this paper, we report the data on antimicrobial susceptibility of 573 isolates of Enterobacteriaceae collected in 25 hospitals of 18 cities of …

Streptococcus pneumoniae strains isolated from children of Krasnoyarsk (Siberia, Russian Federation) were examined. Authors determined Streptococcus pneumoniae serotypes and antimicrobial resistance. 16.7% of strains were multiple resistant with high …

Objective. To study antimicrobial resistance of Haemophilus influenzae and its trends in different Russian regions over the period of 2004–2009. Materials and Methods. This study included consecutive clinical strains of H. influenzae obtained from patients with different infections (pneumonia, acute otitis media, meningitis, bacteremia, COPD exacerbation, etc.) in Central, Volga, Ural, and Siberian federal districts of Russia over the period of 2004–2009. Susceptibility to 12 antimicrobial agents was determined by broth microdilution method according to the Clinical Laboratory Standards Institute guidelines (CLSI 2013).

Infections caused by drug resistant pathogens are ever-increasing problem in hospital and outpatient settings. Nosocomial infections are associated with treatment failures, prolonged length of hospital stay and increased mortality. Chlorhexidine …

We tested antimicrobial susceptibility of retrospective collection of clinical strains group С and G streptococci (69 strains including 58 strains of Streptococcus dysgalactiae subspecies equisimilis and 11 strains of Streptococcus anginosus). …

Objective. Objectives. To study incidence and changes of fluoroquinolone resistance among Mycobacterium tuberculosis in Novosibirsk region, and to determine fluoroquinolone contribution to drug resistance selection in M. tuberculosis population. Materials and Methods. A total of 344 clinical isolates of M. tuberculosis obtained from patients with newly diagnosed tuberculosis during the periods of 2000–2002 and 2006–2010 were tested for susceptibility to fluoroquinolones. This study included 141 isolates susceptible to first-line drugs and 83 isolates resistant to isoniazid and rifampicin (multi-drug resistance [MDR]), and 120 isolates resistant to one or more anti-TB drugs, but without MDR.

The analysis of the results of infectious agents present on a wound was performed and the leading role of staphylococcus was revealed in the burn centre of Nizhny Novgorod Research Institute of Traumatology and Orthopaedics during the period of …

Objective. Objectives. To evaluate the level, structure and phenotypes of antimicrobial resistance in clinical respiratory strains of Streptococcus pyogenes in different regions of Russia during 1999–2009. Materials and Methods. In total 804 respiratory strains of S. pyogenes from different regions of Russia were included in the study. Susceptibility to 18 antimicrobials was evaluated by the standard broth microdilution method according to EUCAST 2012 recommendations. Results. β-Lactams remaine highly active against all tested strains.

At the present article we evaluate a relatively new method of the evaluation of activity of antimicrobials against bacterial biofilms. This method combines the possibilities of simultaneous evaluation of bacterial survival in biofilm in the presence …

Here we report on a high incidence of quinolone resistance (43,1%) among nosocomial CTX-M-5 ESBLproducing S. Typhimurium isolates belonging to a single clonal group isolated in Russia, Belarus, and Kazakhstan. The resistance mechanism in all cases …
