Whole-Genome Draft Assemblies of Difficult-to-Classify Escherichia coli O157 and Non-O157 Isolates from Feces of Canadian Feedlot Cattle.

ABSTRACT: Forty-eight Escherichia coli strains were chosen due to variable detection of stx or serogroup by PCR. Although all strains were initially determined to be Shiga toxin-producing Escherichia coli (STEC), their genomes revealed 11 isolates carrying stx1a, stx1b, stx2a, and/or stx2b Assembled genome sizes varied between 4,667,418 and 5,556,121 bp, with N50 values between 79,648 and 294,166 bp and G+C contents between 50.3% and 51.4%.
