Whole genome analysis of multidrug-resistant isolate collected from drinking water in Armenia revealed the plasmid-borne mediated colistin resistance.

Unlabelled: The rate of polymyxin-resistant , as well as human and animal infections caused by them, is increasing worldwide, posing a high epidemiological threat since colistin represents a last-resort antibiotic to treat complicated infections. The study of environmental niches, in particular, aquatic ecosystems in terms of genome analysis of inhabiting antimicrobial-resistant (AMR) microorganisms as reservoirs of acquired resistance determinants (AMR genes), represents a specific concern from a One Health approach. Here, we present a phenotypic AMR analysis and molecular characterization of isolate found in municipal drinking water after an accident in the water supply system of a residential building in Armenia in 2021.

Plasmid Composition, Antimicrobial Resistance and Virulence Genes Profiles of Ciprofloxacin- and Third-Generation Cephalosporin-Resistant Foodborne Isolates from Russia.

is an important foodborne pathogen worldwide. Ciprofloxacin and extended-spectrum cephalosporins are the common first-line antimicrobial drugs for the treatment of salmonellosis, antimicrobial resistance genes for which are mostly transferred via plasmids. The goal of this work was to perform genomic analysis of plasmids from foodborne isolates obtained in Russia based on whole-genome sequencing.

Whole-Genome Analysis of Isolates from Ready-to-Eat Food in Russia.

This study provides a thorough investigation of a diverse set of antimicrobial resistant (AMR) isolates collected from a broad range of ready-to-eat (RTE) food in various geographic regions of Russia ranging from Pskov to Kamchatka. Thirty-five isolates were characterized using the whole genome sequencing (WGS) analysis in terms of clonal structure, the presence of resistance and virulence determinants, as well as plasmid replicon sequences and CRISPR/Cas systems. To the best of our knowledge, this is the first WGS-based surveillance of Russian RTE food-associated isolates.

Comparative Whole-Genome Analysis of Russian Foodborne Multidrug-Resistant Infantis Isolates.

Non-typhoidal infections remain a significant public health problem worldwide. In this study, we present the first detailed genomic analysis report based on short-read (Illumina) whole-genome sequencing (WGS) of 45 multidrug-resistant (MDR) subsp. serotype Infantis isolates from poultry and meat product samples obtained in Russia during 2018-2020, and long-read (MinION) WGS of five more representative isolates.

[The new possibilities in serologic diagnostic of Ixodes mite-borne borreliosis using ImmunoChip].

The new kit of reagents in format of the immunochip "ImmunoChip Borreliosis" for multiplex serologic analysis of mite-borne borreliosis demonstrated high diagnostic sensitivity and specificity. The percentage of detection of specific immunoglobulins was higher in "ImmunoChip Borreliosis" as compared with screening results in immune enzyme analysis. The high correlation between results of testing in immunochip and data of immune blotting is demonstrated to.
