Practice of local antibiotic resistance monitoring at hospitals in various regions of the Russian Federation

Objective. To analyze the features of local antibiotic resistance monitoring at hospitals in the Russian Federation. Materials and Methods. The study involved a survey of 305 institutions. The duration of data collection was 1 year (March 2020 – April 2021). The responses received were analyzed using the «R» programming language. Special packages were used for data processing and calculation of confidence intervals. Results were assessed by descriptive analysis with calculation of absolute and relative frequencies, and 95% confidence intervals according to the Wilson method.

Antimicrobial resistance and antimicrobial therapy modification during COVID19 pandemic in large tertiary hospital

Objective. assessment of the evolution of the microbiological landscape of the hospital for the period of operation in 2020 into a pandemic of a new coronavirus infection in various departments, including intensive care units; change depending on the results of antibacterial therapy regimens. Materials and Methods. In a retrospective study, conducted from June to December 2020, in a multidisciplinary hospital working with COVID-19 infection, the resistance of isolated strains of microorganisms was analyzed in patients of different age groups.

AMRmap – antibiotic resistance surveillance system in Russia

Objective. To review the basic principles and functionality of the AMRmap online resource. Materials and Methods. The AMRmap platform was developed using the R programming language and various downloadable modules – packages. The current annually updated version of EUCAST clinical breakpoints was applied for determination of categories of susceptibility to antimicrobial agents. Descriptive analysis includes calculation of absolute and relative frequencies, median values, and confidence intervals using the Wilson method.

AMRcloud: a new paradigm in monitoring of antibiotic resistance

Antimicrobial resistance is a growing threat to global public health and requires closer attention from the medical community. Antibiotic resistance monitoring systems play a key role in observing the antimicrobial susceptibility changes for rational …

Genotypes and metallo-beta-lactamases carriage in carbapenem-resistant Pseudomonas aeruginosa isolated from children in Moscow

Objective. To characterize the population structure and determine the genetic mechanisms of carbapenem resistance in nosocomial isolates of P. aeruginosa collected in Moscow in 2012-2016. Materials and methods. Carbapenem-resistant isolates were collected in two pediatric hospitals in Moscow. Antibiotics susceptibility of P. aeruginosa isolates was assessed using the E-tests and disk-diffusion method. Multilocus sequence typing (MLST) was used for genotyping of the isolates. The presence of metallo-betalactamase (MBL) genes was determined using real-time PCR.

Bacteriophage Preparations and Antibiotic Combinations: In vitro Activity Against Extensively Drug-Resistant Isolates of Pseudomonas aeruginosa ST235

The activity of 11 antibiotics combinations and 4 commercially available preparations for phagotherapy in regard to metallo-beta-lactamase (MBL) producing Pseudomonas aeruginosa clinical isolates of sequence type 235 (ST 235) belonging to the clonal …

Ceftibuten in the Treatment of Community-Acquired Urinary Tract Infections in Russia

Objective. Objectives. To investigate etiology and in vitro susceptibility of the most common pathogens causing community-acquired urinary tract infections (UTIs) in Russia. Materials and Methods. A total of 182 uropathogens isolated from urine samples of patients with communityacquired UTI were collected in Russia during 2013–2014 and included in the study. Results. Among the identified microorganisms the most prevalent uropathogens were Enterobacteriaceae (87,9%) and E. coli (68,1%). Drugs active against more than 90% of all Enterobacteriaceae isolates were fosfomycin (98,1%) and ceftibuten (93,1%).
