ABSTRACT NDM-producing Klebsiella pneumoniae strains represent major clinical and infection control challenges, particularly in resource-limited settings with high rates of antimicrobial resistance. Determining whether transmission occurs at a gene, plasmid, or bacterial strain level within hospital and/or the community has implications for monitoring controlling spread. Whole-genome sequencing (WGS) is highest-resolution typing method available epidemiology. We sequenced...
