a
HUS, isolate obtained from HUS patient; cattle, isolate obtained from bovine feces; beef, isolate obtained from beef sample; cheese, isolate obtained from cheese sample.
b
The letters differentiate groups of isolates, and the subscript numbers indicate minor differences between isolates of the same group.
c
The numbers indicate the sizes (in kilobases) of the different stx2 fragments obtained.
d
2, stx2; 2vh-a, stx2vh-a; 2vh-b, stx2vh-b
e
The letters differentiate isolates on the basis of the number and size of the plasmids.
