Complete Genome Sequences of a Stress-Resistant Outbreak-Associated Shiga Toxin-Producing Escherichia coli O157:H7 Strain and a Variant with Enhanced Congo Red-Binding Capability

Abstract

The genome sequences of Escherichia coli O157:H7 strain 380-94, which was isolated from a 1994 dry-cured salami outbreak, and a stronger Congo red-binding variant, RV06, were determined using long-read sequencing technology and de novo assembly. Both strains possessed one chromosome and one plasmid. Strain RV06 possessed a 4,769-bp deletion in the rcs region.
