Enhanced transposition of ISEcp1 carrying blaCTX-M-15 in response to sub lethal levels of ceftazidime, ampicillin and cloxacillin, in E. coli isolated from a dairy farm.

This study aimed to examine the causative factors of the dissemination of cefotaxime resistance from Escherichia coli isolates sampled between October 2017 - January 2018 from a UK dairy farm.
