Draft Genome Sequences of Seven Strains of Shiga Toxin-Producing Escherichia coli O111 with Variation in Their Sensitivity to Novobiocin

Abstract

Inclusion of novobiocin as a selective agent for enrichment media and selective agars inhibits the growth of some Shiga toxin-producing Escherichia coli (STEC) strains, particularly non-O157 STEC, which can yield false-negative detection results. Here, we report the draft genomic sequences of seven STEC O111 isolates with different sensitivities to novobiocin.
