Abstract: Transmission of Antibiotic Resistance at the Wildlife-livestock Interface

Abstract: Transmission of antibiotic resistance at the wildlife-livestock interface

Antibiotic-resistant microorganisms (ARMs) are widespread in natural environments, animals (wildlife and livestock), and humans, which has reduced our capacity to control life threatening infectious disease. Yet, little is known about their transmission pathways, especially at the wildlife-livestock interface. This study investigated the potential transmission of ARMs and antibiotic resistance genes (ARGs) between cattle and wildlife by comparing gut microbiota and ARG profiles of feral swine (Sus scrofa), coyotes (Canis latrans), cattle (Bos taurus), and environmental microbiota. Unexpectedly, wild animals harbored more abundant ARMs and ARGs compared to grazing cattle.

Canadian Roundtable for Sustainable Beef - The National Beef Sustainability Assessment measures the environmental, social and economic performance of Canadian beef. It shows us where we are doing well, and opportunities for improvement. Data from our 2016 study provided key sustainability metrics such as our GHG footprint, our biodiversity contribution, how much carbon is stored in land used for beef production, and much more. We are updating the Assessment and we need input from Canadian beef producers.
