Resistance is not futile: Antibiotic resistance in animal agriculture, from bacterial communities to pathogenic strains.

Dr. Tim Johnson is an Associate Professor of Food Animal Microbiomes in the Department of Animal Sciences at Purdue University. Tim received his PhD from Michigan State University as a member of the Center for Microbial Ecology. He then went on to complete two postdoctoral positions, the first at the Michael G. DeGroote Institute for Infectious Disease Research at McMaster University and then at the Food Safety and Enteric Pathogens Research Unit at the USDA National Animal Disease Center. Tim’s work focuses on antibiotic alternative animal feed additives, understanding and controlling microbiome colonization, the impact of antibiotic use on antibiotic resistance gene ecology in the agroecosystem, and the development of rapid bioassays to provide timely information in the selection of an effective antibiotic.
