Investigation of carbapenemase and mcr-1 genes in carbapenem-resistant Klebsiella pneumoniae isolates

Abstract

OXA-48 and OXA-55 co-harboring isolates and mcr-1 gene (+) isolates were spreading. Automated colistin susceptibility results should be confirmed by microdilution method. Resistance mechanisms in Enterobacteriaceae should be determined and the isolates should be monitored by molecular epidemiological methods. Effective infection control measures will contribute to reduce risk of antibiotic resistant bacterial infections and dissemination of antibiotic resistance.
