Abstrakt: | Objectives: This study delineated the clonal lineages, antibiotic resistome and plasmid replicon types in multidrug-resistant K. pneumoniae isolates from a teaching hospital in Ghana. Methods: Identification and antibiotic susceptibility testing were done using the MALDI-TOF MS and Vitek-2 automated system. Genomic DNA extraction was carried out using the NucliSens easyMAG® (BioMérieux) kits and the DNA was subjected to whole genome sequencing (WGS) using the Illumina MiSeq platform. Results: Of the 200 isolates obtained, 37 were identified as K. pneumoniae of which 9 were resistant to all second and third-generation cephalosporins. These 9 isolates selected for further genomic analysis were characterized by the presence of 8 diverse sequence types (STs), capsular polysaccharide serotypes (K types and wzi allelic types) and multiple genes encoding resistance to β-lactams (bla Conclusions: The varied clonal clusters and resistome identified in the multidrug-resistant K. pneumoniae isolates is a major threat to the management of infections in Ghana. The molecular characterization of antibiotic resistance is thus imperative to inform strategies for containment. (Copyright © 2019 The Authors. Published by Elsevier Ltd.. All rights reserved.) |
