Salmonella enterica

Objective. To analyze frequency and identify genetic determinants of resistance of non-typhoid Salmonella (NTS) producing extended-spectrum β-lactamase (ESBL) isolated in the Russian Federation over the period 2016 to 2020. Materials and Methods. Salmonella isolates, suspected to ESBL production, were collected by the All-Russia Reference Center of Salmonellosis during the national Salmonellosis surveillance program. Phenotypic resistance was determined by the broth microdilution method using G-I and G-II Mikrolatest®SensiLaTest MIC plates and by the double-disk synergy test.

This review contains brief information on the epidemiology of salmonellosis as well as the modern classification and nomenclature of Salmonella genus. The main mechanisms of antimicrobial resistance in Salmonella and their prevalence are summarized. …
