Title: Minimizing Antimicrobial Resistance Transmission: The Dairy Farm as the Model System
Annual Direct Cost: $164,110
Project Period: 09/01/10-08/31/14
DESCRIPTION (provided by applicant): This proposal addresses Special Emphasis Project 111.I, “Minimizing antibiotic resistance transmission throughout the food chain.” The proposed project will use the dairy production environment as a model for understanding the occurrence of antibiotic resistance. Dairy cattle are considered an important source of human infections with multidrug-resistant Salmonella and other pathogens. Calf-raising facilities are important “selection foci” (where pathogens and commensals are readily transmitted in an environment characterized by a high degree of antimicrobial drug use), and animal movements among dairy farms play a critical role in the dissemination of resistant pathogenic bacteria. Complex communication structures on large dairy farms are barriers to the implementation of policies that would promote judicious antibiotic use and improvements in biosecurity. However, the extent to which on-farm reductions in resistance selection and transmission will impact human health us unknown.
