BKC-2, a New BKC Variant Detected in MCR-9.1-producing Enterobacter hormaechei subsp. xiangfangensis.

Abstract:

:We performed the characterization of a multidrug-resistant (MDR) Enterobacter spp. isolate highlighting the genetic aspects of the antimicrobial resistance genes. An Enterobacter spp. isolate (Ec61) was recovered in 2014 from a transtracheal aspirate sample from a patient admitted to a Brazilian tertiary hospital and submitted to further microbiological and genomic characterization. Ec61 was identified as Enterobacter hormaechei subsp. xiangfangensis ST451, showed a MDR profile and the presence of genes codifying new β-lactamase variants, BKC-2 and ACT-84, and the mobile colistin resistance gene mcr-9.1.
