Pseudomonas aeruginosa High-Risk Sequence Type 463 Co-Producing KPC-2 and AFM-1 Carbapenemases, China, 2020-2022.

ABSTRACT

We report the clonal spread and evolution of high-risk Pseudomonas aeruginosa sequence type 463 co-producing KPC-2 and AFM-1 carbapenemases isolated from hospital patients in China during 2020-2022. Those strains pose a substantial public health threat and surveillance and stricter infection-control measures are essential to prevent further infections.
