Antimicrobial Resistance

Acinetobacter baumannii and related species of the A. baumannii complex are the common and one of the most difficult-to-treat nosocomial pathogens. In this paper, we report the data on antimicrobial susceptibility of 568 isolates of Acinetobacter …

Pseudomonas aeruginosa is the most abundant bacterial species causing nosocomial infections in Russia. In this paper, we report the data on antimicrobial susceptibility of 743 isolates of P. aeruginosa collected in 63 hospitals of 22 cities of Russia …

colonization of gastric mucosa with Helicobacter pylori in patients with precancerous conditions (adenomatous polyp, hyperplastic polyp, focal hypertrophy, erosions) and gastric cancer (adenocarcinoma, signet ring cell carcinoma, carcinoid). The …

Objective. of current Neisseria gonorrhoeae isolates and determine its trends over the RU-GASP (Russian Gonococcal Antimicrobial Susceptibility Programme) period. Materials and Methods. A total of 293 strains of N. gonorrhoeae isolated in 11 regions within Central, North-Western, Volga, Southern, and Siberian federal districts over the 2015–2016 were included in this study. Susceptibility to benzylpenicillin, ceftriaxone, tetracycline, spectinomycin, azithromycin, and ciprofloxacin was determined by agar dilution method and assessed according to the CLSI, EUCAST and MUK 4.

Acquired bacterial resistance is one of the leading causes of morbidity and mortality attributed to infectious diseases. Simulations may provide opportunity to predict further spread of resistance and, to some extent, manage it. The objective of this …

Carbapenem-resistant nosocomial K. pneumoniae isolates are a significant problem in clinical practice. Carbapenem resistance in K. pneumoniae isolated from hospitalized patients was 2.8% over the study period. NDM-1 carbapenemase-producing strains …

This study was aimed to determine isolation rate of H. pylori from gastric mucosal biopsies in 869 patients with chronic gastritis and gastric peptic ulcers in Republic of Tatarstan during the 2008–2013. A total of 45.5% of gastric biopsy samples …

The resistance of the systemic Candida infections causative agents is a cornerstone of the selection of an effective therapy. But if before the problem was limited to resistance to azole antifungals, then by now we have enough data about cases of …

Objective. To assess antimicrobial resistance of gram-negative microorganisms causing complicated intra-abdominal infections (IAI) in Russia. Materials and Methods. This was a multicenter (a total of 21 cities), prospective, microbiological study to collect Gram-negative pathogens from patients with complicated IAI. Identification was performed using MALDITOF mass spectrometry. Minimal inhibitory concentrations (MICs) of antibiotics were determined by dilution method according to the current CLSI and EUCAST guidelines. Results. A total of 1908 isolates of gram-negative pathogens was obtained (357 isolates in community-acquired IAI, and 1551 isolates in nosocomial IAI).

Background. Ceftaroline is a new broad-spectrum cephalosporin with in vitro activity against Gram-positive pathogens, including MRSA, and common Gram-negative pathogens. It is approved for the treatment of acute complicated bacterial skin and skin-structure infections (SSSIs) and community-acquired bacterial pneumonia. Objective. To determine in vitro activity of ceftaroline and other clinically available antimicrobials against major bacterial pathogens from different regions of Russian Federation. Materials and Methods. A total of 2778 consecutive, non-duplicate isolates were collected during multicentre microbiological in vitro study from 36 geographically distinct cities of Russia during 2008–2012.
