Abstract Aim Although carbapenem is the last-resort drug for treating drug-resistant Gram-negative bacterial infections, prevalence of carbapenem-resistant bacteria has substantially increased worldwide owing to irrational use of antibiotics particularly in developing countries like Nepal.  Therefore, this study was aimed to determine the prevalence of carbapenemase-producing K. pneumoniae and to detect the carbapenemase genes (blaNDM-2 and blaOXA-48) in at a tertiary care hospital in Nepal. Materials and methods A hospital-based cross-sectional study was carried out from June 2018 to January 2019 at the Microbiology Laboratory of Annapurna Neurological Institute and Allied Sciences, Kathmandu, Nepal. Different clinical samples were collected and cultured in appropriate growth media. Biochemical tests were performed for the identification of K. pneumoniae. Antibiotic susceptibility testing (AST) was performed by the Kirby–Bauer disc diffusion method. The modified Hodge test (MHT) was performed to detect carbapenemase producers. The plasmid was extracted by the modified alkaline hydrolysis method. Carbapenemase-producing K. pneumoniae were further confirmed by detecting blaNDM-2 and blaOXA-48 genes by PCR using specific forward and reverse primers followed by gel electrophoresis. Results Out of the total 720 samples, 38.9% (280/720) were culture positive. K. pneumoniae was the most predominant isolate 31.4% (88/280). Of 88 K. pneumoniae isolates, 56.8% (50/88) were multi-drug resistant (MDR), and 51.1% (45/88) were MHT positive. Colistin showed the highest sensitivity (100%; 88/88), followed by tigecycline (86.4%; 76/88). blaNDM-2 and blaOXA-48 genes were detected in 24.4% (11/45) and 15.5% (7/45) of carbapenemase-producing K. pneumoniae isolates, respectively. Conclusion The rate of MDR and carbapenemase production was high in the K. pneumoniae isolates. Colistin and tigecycline could be the drug of choice for the empirical treatments of MDR and carbapenemase-producing K. pneumoniae. Our study provides a better understanding of antibiotic resistance threat and enables physicians to select the most appropriate antibiotics.

Abstract Background Evaluating the expression pattern of oxacillinases (OXA) carbapenemases is essential to understand the prevalence and spread of carbapenem resistance Acinetobacter baumannii. Objectives The aim of the study is to evaluate the presence of OXA carbapenemase genes and ISAba1 upstream to these genes in carbapenem-resistant A. baumannii clinical isolates. Material and Methods A. baumannii isolated from clinical samples were phenotypically identified and antibiotics sensitivity was performed. Multiplex polymerase chain reaction (PCR) was used to detect OXA51-like gene, OXA carbapenemases genes (OXA-23-like, OXA-24-like, and OXA-58-like), and ISAba1 in carbapenem-resistant isolates. Results Out of 55 Acinetobacter isolates, 54 were confirmed as A. baumannii by PCR. Bla OXA-23-like gene was observed in 51 isolates of A. baumannii and none of the isolates showed the presence of bla OXA-24-like and bla OXA-58-like genes. Presence of ISAba1 upstream to OXA-23-like gene, OXA-51-like gene, and both OXA-51-like/OXA-23-like genes was observed in 51, 7, and 4 A. baumannii isolates, respectively. Conclusion The genetic pattern of carbapenem-resistant A. baumannii isolated in this study was unique, which should be factored for clinical protocols to manage infections caused by emerging resistant strains of A. baumannii.
