Detection Sequencing NDM and blaOXA Genes in Metallo-$\beta$-Lactamase Producing Klebsiella Pneumoniae

Abstract

The prevalence of Carbapenem-resistance in Enterobacteriaceae is rising worldwide and poses a treatment challenge for healthcare facilities. This study aims to detect a sequence of New Delhi metallo- -lactamase (NDM) and bla OXA-48 gene in metalo-beta-lactamase-producing Klebsiella pneumoniae isolated from a few hospitals in the city of Baghdad. 74 Klebsiella pneumoniae were isolated from 320 clinical samples that were routinely submitted to the diagnostic laboratory of the chosen hospital. These samples included sputum, tissue swabs, folly tips, urine, ear swabs, bloodstream, pus, wound swabs, endotracheal tubes, and body fluids. In this study, 74 isolates were examined for expression of carbapenemase by phenotyping method. The modified Hodge Test (MHT) is utilized for phenotypic detection. MHT was positive for 24 carbapenem-resistant Klebsiella pneumoniae. Genotyping was accomplished by using polymerase chain reaction (PCR) to amplify target genes by employing particular primers. The NDM gene was detected in 19/24 isolates, and the blaOXA-48 gene was detected in 5/24 isolates. The presence of bla NDM and the dangerously high frequency of MBL in the Klebsiella pneumoniae strain are both concerning, and it has been demonstrated to be challenging to treat and inhibit infection.
