摘要：

We compared the magnitude and duration of fecal shedding of wild-type Escherichia coli O157:117 to that of an isogenic intimin mutant in young adult cattle and sheep. In both rum in ant species, wild-type E. coli O157:H7 was shed in greater numbers and for a longer duration than was the intimin mutant.
