Emerging antimicrobial resistance among Escherichia coli strains in bloodstream infections in Toronto, 2006-2016: a retrospective cohort study.

ABSTRACT:

Background

Enterobacteriaceae that produce extended-spectrum β-lactamase (ESBL) have emerged as a serious threat, with variable rates depending on geographic region. We determined the prevalence of ESBL-producing Escherichia coli, Klebsiella pneumoniae, K. oxytoca and Proteus mirabilis in bloodstream infections in Toronto from 2006 through 2016.

Methods

All patients with E. coli, K. pneumoniae, K. oxytoca and P. mirabilis isolated from blood in a tertiary care microbiology laboratory in Toronto between 2006 and 2016 (1 isolate per species per patient per year) were included in this retrospective cohort study. Organisms were identified by conventional methods, and susceptibility testing was performed according to Clinica
