Antimicrobial Drug-Resistant Shiga Toxin-Producing Escherichia coli Infections, Michigan, USA

Emerg Infect Dis. 2017 Sep;23(9):1609-1611. doi: 10.3201/eid2309.170523.

Abstract

High frequencies of antimicrobial drug resistance were observed in O157 and non-O157 Shiga toxin-producing E. coli strains recovered from patients in Michigan during 2010-2014. Resistance was more common in non-O157 strains and independently associated with hospitalization, indicating that resistance could contribute to more severe disease outcomes.

Keywords: Escherichia coli; Michigan; STEC; Shiga toxin–producing E. coli; United States; antibiotic resistance; antimicrobial resistance; bacteria; epidemiology; risk factors.
