a

A total of 338 STEC isolates from ground beef were analyzed for the presence of the four OIs shown. Any isolates containing a genetic marker indicating the presence of an OI are listed.

b

Within OI-71, six genes were targeted (nleG, nleG9, nleF, H1-2, nleA, and G2-1), but H1-2 and G2-1 were not detected in any isolate; therefore, these markers are not listed.

c

All other STEC isolates contained intimin (eae), whereas this isolate contained subtilase (subA).
