antimicrobial resistance

Objective. Creation and evaluation of the effectiveness of an integrated system for automatic validation of microbiological reports and monitoring of antimicrobial resistance (AMR) on real time at the regional level within the Yamalo-Nenets Autonomous Okrug (YNAO). Materials and Methods. The prospective study was conducted from October 2023 to June 2025, based on the Medical Information and Analytical Center and five largest hospitals in the YNAO. The study design included a comparative analysis of AMR monitoring status before and after the implementation of the digital platform.

Objective. To determine the population structure of clinical P. aeruginosa isolates recovered from hospitals in different regions of Russia and to assess the role of high-risk clones in the dissemination of carbapenemases and carbapenem resistance. Materials and Methods. The study included consecutive, non-duplicate clinical isolates of P. aeruginosa (N = 1379) obtained from 55 hospitals across 30 Russian cities over a 24-month period. Species identification was performed using MALDI-TOF mass-spectrometry.

Objective. To evaluate level of knowledge, attitudes, and practices (KAP) concerning sepsis and antimicrobial resistance (AMR) among medical students in the Russian Federation. Materials and Methods. A multicenter, cross-sectional survey was conducted among students from six medical universities using a validated questionnaire (Cronbach’s alpha: 0.74) developed based on the Knowledge, Attitudes, and Practices (KAP) model. Results. The study included 1052 respondents, comprising 315 (29.9%) males and 737 (70.1%) females, with a median age of 22 [21; 24] years.

Objective. To implement a closed digital loop for continuous antimicrobial resistance (AMR) surveillance based on validated microbiological diagnostic results. Materials and Methods. A prospective study was conducted at the Federal State Autonomous Institution «National Medical Research Center for Treatment and Rehabilitation» of the Ministry of Health of the Russian Federation from May 2024 to September 2025. An audit of the initial state of processes, a SWOT analysis, software restructuring, data flow optimization and standardization of diagnostic methods in accordance with EUCAST recommendations were performed.

The problem of antimicrobial resistance represents one of the most urgent and complex problems of modern healthcare. The measures that are being taken today to control antimicrobial resistance, however, cannot be considered satisfactory, and we are …

Objective. To study susceptibility of clinical Bacteroides spp. and Clostridium perfringens isolates to antimicrobial agents across different regions of the Russian Federation and to identify regional patterns of antimicrobial resistance. Materials and Methods. The study included 1,685 isolates of obligate anaerobic bacteria belonging to 107 species, isolated from patients in 60 regions of the Russian Federation during period from January 2023 to December 2024. Among them, 144 C. perfringens isolates from 37 regions, and 370 Bacteroides spp.

In modern literature, there is insufficient information on the composition of the conjunctival microbiota in children under 1 year of age, and information on its composition in premature infants is virtually absent. Analysis of conjunctival …

Objective. To analyze antimicrobial susceptibility of representatives of the genus Streptococcus in different wards of a multidisciplinary hospital. Materials and Methods. Epidemiological observational descriptive continuous retrospective survey was conducted. Antimicrobial susceptibility data on 2916 streptococcal isolates obtained from the laboratory information system «ALISA» were analyzed for the period from 01.01.2017 to 31.12.2022. Antimicrobial susceptibility testing was performed using BD Phoenix M50, interpretation of susceptibility testing results was done in accordance with EUCAST recommendations.

Objective. To study antimicrobial effect of extracellular metabolites of probiotic L. plantarum 8P-A3 strain on antibiotic-resistant Klebsiella pneumoniae and Acinetobacter baumannii isolated from infected wounds. Materials and Methods. Bacteriological methods: semiquantitative sector method for extracting opportunistic microorganisms from an infected wound; a method for the identification of the antimicrobial activity of metabolites in a liquid milieu; The identification of bacteria was implemented with the help of the MALDI-TOF Autoflex mass spectrometer (Bruker Daltonics, Germany).

Objective. To analyze and compare multidrug-resistant Klebsiella pneumoniae (KP) strains isolated from different sites of the same patients. Materials and Methods. A total of 30 KP strains isolated from 15 patients treated in intensive care and surgical units in 2020–2021 were studied. Two strains isolated from one child were selected for analyses. One strain was isolated from a clinically significant site (blood/urine/wound/endotracheal aspirate or sputum), the other from a monitoring site (stool).
