  • a Bovine O157 isolates with designations highlighted in bold were used for MLST analysis.

  • b EHEC, stx and eae positive; EPEC, eae positive; AT, atypical (eae and stx negative).

  • c NT, nontypeable; R, phage resistant; NC, noncharacteristic PT; d, derivative.

  • d Identified as O157 and rfbE positive by PCR and by latex agglutination and as O rough by tube agglutination.
