Objective. To evaluate in vitro activity of biapenem and other clinically available carbapenems against Russian clinical isolates of Enterobacterales, Pseudomonas aeruginosa и Acinetobacter spp., including isolates with acquired fermentative mechanisms of resistance to β-lactams. Materials and Methods. A total of 3139 Enterobacterales isolates, 793 P. aeruginosa isolates and 634 Acinetobacter spp. isolates from hospitalized patients in 63 hospitals from 35 Russian cities were included in the study during 2018-2019. Minimal inhibitory concentrations (MIC) for biapenem and other antimicrobials were determined in accordance with ISO 20776-1:2006.

Objective. To assess the in vitro activity of ceftazidime-avibactam against clinical Enterobacterales and Pseudomonas aeruginosa isolates in various regions of Russia based on results of local susceptibility testing by disk diffusion method. Materials and Methods. Overall, 160 laboratories located in 61 Russian cities participated in this surveillance during 2018-2020. All consecutive clinical isolates of Enterobacterales and Pseudomonas aeruginosa in each participating laboratory were included in the study. Ceftazidime-avibactam susceptibility testing was done by disc-diffusion method in accordance with current EUCAST recommendations.

Objective. To determine species, sequence-types, antimicrobial resistance and virulence genes in Achromobacter spp. isolates obtained from cystic fibrosis (CF) patients in Russia. Materials and Methods. Samples (sputum, nasopharyngeal swab) from 168 CF patients from 48 regions were studied. Whole-genome sequencing (WGS) was performed on MGISEQ-2000 platform. SPAdes software, Galaxy, ResFinder, Integrall, PubMLST were used for analysis of WGS data. Results. A total of 18 strains of Achromobacter spp. were isolated from 16 of 168 CF patients.

The purpose of the meeting is to obtain an opinion on approaches and recommendations for vaccine prevention of pneumococcal infections in adults.

This article is an overview of the data on bacterial intestinal translocation. The article reviews changes in the intestinal microbiome, the local physiological barrier, as well as the innate and adaptive immunity characteristics contributing to the …

Objective. To determine type of cytomegalovirus (CMV) infection (reactivation of a virus strain that was present before transplantation or re-infection with another virus strain) in allogeneic hematopoietic stem cell recipients by sequencing. Materials and Methods. Clinical and laboratory data of 179 recipients of allogeneic hematopoietic stem cells collected from 2014 to 2018 were analyzed for CMV DNA in clinical specimens before and after transplantation. A total of 14 patients (28 samples) were included in the study.
