Genome sequencing and comparative analysis of an NDM-1-producing Klebsiella pneumoniae ST15 isolated from a refugee patient

AbstractThe escalating problem of antibiotic resistance, specifically cabarpenemase and extended-spectrum β-lacatamase (ESBL) producing K. pneumoniae strains, is directly correlated with increased patient morbidity and mortality and prolonged hospitalization and costs. In this study, a comprehensive genomic analysis encompassing the resistomics, virulence repertoire and mobile genetic elements of an NDM-1 positive ESBL-producing K. pneumoniae EA-MEH ST15 isolated from a urine sample collected from a Syrian refugee was conducted. Illumina paired-end libraries were prepared and sequenced resulting in 892,300 high-quality reads. The initial assembly produced 329 contigs with a combined 5,954,825 bp and a 56.5% G+C content. Resistome analysis revealed the presence of several β-lactamases including NDM-1, SHV-28, CTX-M-15 and OXA-1 in addition to 18 other genes encoding for resistance, among which are aph(3′)-Ia, aac(6′)Ib-cr, armA, strB, strA and aadA2 genes. Additionally, five plasmids IncFIB(Mar), IncHI1B, ...
