Abstract

Shiga toxin-producing Escherichia coli (STEC) strains are important foodborne pathogens associated with human disease. Most disease-associated STEC strains carry the locus of enterocyte effacement (LEE); however, regularly LEE-negative STEC strains are recovered from ill patients. Few reference sequences are available for these isolate types. Here, we report here the complete genome sequences for four LEE-negative STEC strains.
