Antimicrobial Resistance

The prevalence and molecular epidemiology of MBLproducing Gram-negative bacteria have been studied in Russia (1998–2010), Belarus and Kazakhstan (2005– 2010). Analysis of nosocomial strains isolated as part of several multicentre surveillance studies …

Different mechanisms of antimicrobial resistance development in biofilm bacteria are reviewed in the article. Practical approaches to the susceptibility testing of bacteria in biofilms are analyzed.

In this paper, the evidence of broad geographic dissemination of Salmonella enterica serovar Typhimurium strains belonging to a single genetic lineage is presented. The isolates described possess resistance to oxiiminocephalosporines due to …

Methicillin-resistant Staphylococcus aureus (MRSA) ST239 is one of the most common nosocomial genotypes worldwide. Typical MRSA ST239 strains do not produce toxic shock syndrome toxin-1 (TSST-1), which is encoded by tst gene at staphylococcal …

Antimicrobial susceptibility, serotype distribution, and multilocus sequence types of Streptococcus pneumoniae isolated from the patients with meningitis were determined. We tested a total of 84 isolates which have been obtained in Moscow during …

This article presents results of the study on serotypes distribution of clinical and colonized strains of S. pneumoniae circulated in different regions of Russian Federation in children attended day-care centers and orphanages, and in pediatric …

Objective. To investigate spectrum and antimicrobial susceptibility of colonic microorganisms isolated from biopsy samples in patients with ulcerative colitis. Materials and Methods. A total of 34 patients with ulcerative colitis (19 to 75 years of age) treated in proctology unit (Surgery Clinic of Samara State Medical University) during the 2009–2010 were examined in this study. Results. A total of 70 gram-negative isolates were obtained, of which Enterobacteriaceae were the most predominant pathogens.

Objective. To assess antimicrobial resistance and its trends among Streptococcus pneumoniae in different regions of Russia over the 1999-2009. Materials and Methods. A total of 2419 S. pneumoniae strains from different cities of Central, NorthWestern, Southern, Volga, Ural, Siberia, Far-Eastern regions of Russia were included into the study over the period from 1999 to 2009. Susceptibility to 23 antimicrobials was determined using microdilution method according to Clinical and Laboratory Standards Institute (CLSI) guidelines.

Analysis of susceptibility to carbapenems of P. aeruginosa (n=178) isolated in different Perm city hospitals showed that the majority of carbapenem-resistant strains were obtained from intensive care units (ICU) patients in surgical hospitals. The …

At present, primary, secondary, and multiple resistance of H. pylori to antimicrobial agents tends to increase, which significantly affects efficacy of eradication therapy. There were found significant differences in antimicrobial resistance of H. …
