Antimicrobial resistance, carbapenemase production, and genotypes of nosocomial Pseudomonas aeruginosa isolates in Russia: results of multicenter epidemiological study “MARATHON 2015–2016”

Abstract

Objective. Objectives. To assess the rates of antibiotic resistance, production of acquired carbapenemases, genotypes and prevalence of «international high-risk clones» among nosocomial strains of Pseudomonas aeruginosa isolated in various regions of Russia within the «MARATHON 2015–2016» study. Materials and Methods. A total of 1006 non-duplicate nosocomial isolates of P. aeruginosa collected in 44 hospitals from 25 cities in Russia in 2015–2016 were studied. Species identification of isolates was performed by means of MALDI-TOF mass-spectrometry.
