The global emergence of carbapenem-resistant Klebsiella pneumoniae (CRKP) has become a critical public healthcare concern due to treatment challenges and high mortality. In recent years, there been an increase in cases CRKP co-producing New Delhi metallo-β-lactamases (NDM) oxacillinase 48 (OXA-48)-like carbapenemases the US. aim this study was correlate clinical genomic characteristics NDM OXA-...

Conjugative transposons in Gram-negative bacteria have a significant role the dissemination of antibiotic-resistance-conferring genes between bacteria. This study aims to genomically characterize plasmids and conjugative carrying integrons clinical isolates Klebsiella pneumoniae. The genetic composition phenotypic assessment 50 multidrug-resistant K. pneumoniae from tertiary-care hospital (SQUH...

METHODS Twenty-seven clinical isolates of carbapenem-resistant Klebsiella pneumoniae with MICs ≥4 mg/L for imipenem or meropenem were obtained from inpatients in a hospital in Vietnam. Antimicrobial susceptibility tests and whole genome sequencing were performed. Multilocus sequence typing and the presence of drug resistant genes were determined and a maximum-likelihood phylogenetic tree was co...

Enterobacteriaceae species are important human pathogens while increasing number of antibiotic resistant strains are detected worldwide. The most common antibiotic resistance in Enterobacteriaceae is observed against beta-lactams, fluoroquinolones, aminoglycosides while recently resistance to polymyxins has also appeared. Beta-lactam resistance is mainly conferred by beta-lactamases, capable to...

Adequate detection of the production of carbapenemase in Enterobacteriaceae isolates is crucial for infection control measures and the appropriate choice of antimicrobial therapy. In this study, we investigated the frequency of false positive results for the detection of carbapenemases in carbapenemase-negative Escherichia coli and Klebsiella pneumoniae clinical isolates by the modified Hodge t...

INTRODUCTION Acinetobacter spp. have emerged as notorious pathogens involved in healthcare-associated infections. Carbapenems are important antimicrobial agents for treating infections due to multidrug resistant Acinetobacter spp. Different mechanisms may confer resistance to these drugs in the genus, particularly production of class D carbapenemases. OXA-23-like family has been pointed out as ...
