title: Genetic diversity among Escherichia coli O157:H7 isolates from Bovines living on farms in England and Wales.
abstract: Pulsed-field gel electrophoresis of Escherichia coli O157:H7 isolates (n = 228) from 122 healthy animals on 11 farms discriminated 57 types. Most clones were found only on individual farms. Numerous clones were found within each farm, with a prevalent clone normally found in several animals. A variety of clones were found within the different phage types.
