H. Oppegaard et al., Horizontal transfer of a multi-drug resistance plasmid between coliform bacteria of human and bovine origin in a farm environment, APPL ENVIR, 67(8), 2001, pp. 3732-3734
Multi-drug-resistant coliform bacteria were isolated from feces of cattle e
xposed to antimicrobial agents and humans associated with the animals. Isol
ates from both cattle and humans harbored an R plasmid of 65 kb (pTMS1) tha
t may have been transferred between them due to selective antibiotic pressu
re in the farm environment.
