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

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.
