Emergent Escherichia coli of the highly virulent B2-ST1193 clone producing KPC-2 carbapenemase in ready-to-eat vegetables.

ABSTRACT:

Objectives

Critical priority carbapenem-resistant pathogens constitute a worldwide public health problem. Escherichia coli (E. coli) ST1193 is an emerging high-risk clone that demonstrates prolonged gut persistence, and association with community-onset urinary and bloodstream infections. The purpose of this study is to report microbiological and genomic data on the emergence of KPC-2-producing E. coli ST1193 in ready-to-eat (RTE) vegetables.

Methods

RTE vegetables were purchased from markets in southeastern Brazil. Epiphytic and endophytic Gram-negative bacteria displaying resistance to broad-spectrum beta-lactams were identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry. Whole-genome sequence was conducted using the Illumina NextSeq pla
