Production of Carbapenemases in Klebsiella pneumoniae Isolated in Saint-Petersburg

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 …

Responsible Use of Antibiotics in Food Animals

Antimicrobial use in food animal medicine has become an important political and scientific issue, especially in relation to the contribution that animal sourced antimicrobial resistance might play in human medicine, leading to calls at a political …

Primary Antimicrobial Resistance among Helicobacter pylori Isolated in the Republic of Tatarstan in the 2008–2013

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 …

Multidrug-Resistant Enterobacteriaceae Colonizing Gastrointestinal Tract in Infants with Congenital Heart Disease on Admission to Cardiac Surgery Hospital

We studied 126 children, admitted to cardiac surgery hospital with colonization of the gastrointestinal tract (GIT) by multidrug-resistant Enterobacteriaceae. Criterion for inclusion in the study were children with complex congenital heart disease …

Antimicrobial Resistance of Microorganisms Causing Chronic Post-Traumatic Osteomyelitis

This paper presents the results of a microbiological study of clinical specimens obtained from 64 patients with chronic post-traumatic osteomyelitis of long bones during the 2011–2013. A total of 136 clinical strains were isolated and identified to a …

Surveillance of Activity of Netilmicin in Comparison with Other Antimicrobials against Russian Ophtalmic Bacterial Isolates

Objective. Aim. To evaluate current susceptibility patterns of the potential ocular bacterial pathogens to netilmicin in comparison with other antimicrobials in Russia. Materials and Methods. Overall in the study were included 200 S. aureus strains (100 — MRSA), 50 — coagulase-negative staphylococci, 50 — P. aeruginosa, 50 — Acinetobacter spp., and 50 — Enterobacteriaceae strains, isolated from outpatients and inpatients located in 17 cities of different regions of Russia during 2010–2014.

Antimicrobial Resistance of Gram-negative Microorganisms Causing Complicated Intra-abdominal Infections in Russia

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).

Antimicrobial Susceptibility of Group A Streptococci of Different emm Genotypes, Isolated from Patients with Invasive and Non-Invasive Skin and Soft Tissue Infections

Objective. Aim. To evaluate the antimicrobial susceptibility of group A streptococci (GAS) of different emm-genotypes, isolated from patients with invasive and non-invasive skin and soft tissue infections. Materials and Methods. Overall 91 strains of GAS isolated during 2008–2011 from patients with invasive and non-invasive skin and soft tissue infections hospitalized in one Moscow’s hospital were included in the study. Identification was done by latex agglutination, genotyping — by CDC protocol.

«Checkerboard Array» as a Test for Evaluation of Decrease in Gram-Negative Bacteria Resistance to Carbapenems in the Presence of Bisphosphonate

One of the main mechanisms of resistance of Gramnegative microorganisms to antibiotics is enzymatic hydrolysis by beta-lactamases (for example, metallobeta-lactamases). Searching of paths of strengthening of carbapenems action is possible due to …

Etiology of Infective Endocarditis in Russia

Objective. To investigate etiology of infective endocarditis in Russian Federation. Materials and Methods. Multicenter prospective (September 2011 to December 2013) and retrospective (January 2006 – September 2011) studies to investigate etiology of infective endocarditis (IE) were performed at medical institutions in 10 Russian cities. Patients with definite or possible diagnosis of IE who have at least 1 blood culture collected were enrolled in the study. Results. A total of 401 patients with IE were included in the analysis: 161 (40.
