Whole-Genome Draft Sequences of Six Commensal Fecal and Six Mastitis-Associated Escherichia coli Strains of Bovine Origin.

The bovine gastrointestinal tract is a natural reservoir for commensal and pathogenic Escherichia coli strains with the ability to cause mastitis. Here, we report the whole-genome sequences of six E. coli isolates from acute mastitis cases and six E. coli isolates from the feces of udder-healthy cows.
