Abstract

In this study, we described the carbapenem blaNDM-5-carrying extensive drug-resistant (XDR) K. pneumoniae ST437 from an urban river water Kathajodi in Odisha, India. The presence of carbapenem and co-occurrence of other resistance determinants (blaNDM-5, blaCTX-M, blaSHV, and blaTEM), virulence factors (fimH, mrkD, entB, irp-1, and ybtS), and capsular serotype (K54) represent its pathogenic potential. The insertion sequence ISAba125 and the bleomycin resistance gene bleMBL at upstream and downstream, respectively, could play a significant role in the horizontal transmission of the blaNDM-5. Its biofilm formation ability contributes toward environmental protection and its survivability. MLST analysis assigned the isolate to ST437 and clonal lineage to ST11 (CC11) with a single locus variant. The ST437 K. pneumoniae, a global epidemic clone, has been reported in North America, Europe, and Asia. This work contributes in understanding of the mechanisms behind the spread of blaNDM-5 K. pneumoniae ST437 and demands extensive molecular surveillance of river and nearby hospitals for better community health.
