Spread of tetracycline resistance genes at a conventional dairy farm

Original language description

The use of antibiotics in animal husbandry contributes to the worldwide problem of increasing antibiotic resistance in animal and human pathogens. Intensive animal production is considered an important source of antibiotic resistance genes released to the environment, while the contribution of smaller farms remains to be evaluated. Here we monitor the spread of tetracycline resistance (TC-r) genes at a middle-size conventional dairy farm, where chlortetracycline (CTC, as intrauterine suppository) is prophylactically used after each calving. Our study has shown that animals at the farm acquired the TC-r genes in their early age (1?2 weeks), likely due to colonization with TC-resistant bacteria from their mothers and/or the farm environment. The relativeabundance of the TC-r genes tet(W), tet(Q), and tet(M) in fresh excrements of calves was about 1?2 orders of magnitude higher compared to heifers and dairy cows, possibly due to the presence of antibiotic residues in milk fed to calves.
