Abstract
Escherichia coli O157:H7 is frequently isolated from cases of diarrhea in many industrialized countries; however, it is seldom found in developing countries. The present manuscript reports the presence of E. coli O157:H7 in Ecuadorian livestock, a country where enterohemorrhagic E. coli disease in humans has never been reported. The Ecuadorian isolates were genetically related to some strains linked to clinical cases in the United States as assessed by multiple-locus variable number tandem repeat (VNTR) analysis.
