Phenotypic and genomic characteristics of clinical IMP-producing Klebsiella spp. Isolates in China

Antibiotic resistance occurs when bacteria evolve to withstand antibiotic drugs. We are aware that a bacteria called Klebsiella is rapidly becoming resistant to carbapenems, a class of broad-spectrum antibiotics. In this study, we conducted a genetic and microbiological surveillance study across 13 provinces of China to understand factors that contribute to the growing bacterial drug resistance. We find that the way the multiple bacterial types interact with each other and swap certain genetic material may be the main cause of growing resistance. These findings call for close monitoring of genetic evolution as a matter of public health management strategy.
