Genetic characteristics of antimicrobial resistance mechanisms in Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii isolated from blood and cerebrospinal fluid of children

Abstract

Objective. To assess antimicrobial susceptibility, presence of resistance genes and determine the phenotypic groups of K. pneumoniae, P. aeruginosa and A. baumannii isolated from blood and cerebrospinal fluid of children with nosocomial infections in intensive care units from 2014 to 2020. Materials and methods. Minimum inhibitory concentrations of antibiotics were determined using the serial broth microdilution method. The identification of genes encoding the production of carbapenemases was carried out using hybridization fluorescence detection.
