To test the hypothesis that animal movements played arole in the dissemination of CTX-M ESBL E. coli, two groups of farms were selected. The first consisted of dairy farms with links through animal movements to a known CTX-M ESBL positive farm. Seventeen linked' farms were ultimately recruited to the study. The second, control group, consisted of dairy farms from the same geographical area but with no known link. 48 control farms were successfully enrolled onto the study.

At each visit samplers aimed to collect 30 floor faecal samples from pens occupied by calves (up to 6 months of age) and at least 25 floor (pat) samples from buildings or fields occupied by the adult milking herd.
