Sheep were inoculated with an E. coli O157:H7 strain containing an Stx2-encoding bacteriophage (Phi 3538) in which a chloramphenicol-resistant gene, cat, is inserted into stx(2)." "A total of 149 faecal samples were sampled and analysed for detection and quantification of E. coli O157:H7 and presumptive transductants.
