Prevalence of carbapenemase-producing <i>Klebsiella pneumoniae</i> in the Gomel Region

Abstract

Aim. Within the microbiological monitoring program, to study the prevalence of carbapenemase-producing K. pneumoniae in the healthcare organizations of the Gomel region and assess their level of resistance to antibacterial drugs. Materials and methods. For 91 clinical isolates of Klebsiella pneumoniae with multiple antibiotic resistance, isolated in Gomel and Gomel region, carbapenemase genes were detected by real-time PCR and sensitivity to antibacterial drugs was determined. Results. 68 carbapenemase producers were revealed: KPC — 1 isolate, OXA-48 — 47 isolates, NDM — 20 isolates. Carbapenemase producers were found in 11 Gomel health organizations and 8 central district hospitals of the regional centers of the Gomel region. All of them had an associated resistance to most antibiotics and retained sensitivity to colistin (91.2% sensitive isolates) and tigecycline (98.5%). Conclusion. The spread of carbapenemase-producing K. pneumoniae isolates in healthcare organizations makes it very difficult to conduct effective antibiotic therapy for patients and requires the introduction of appropriate infection control measures aimed at limiting their circulation in the hospital environment.
