With animals being recognized as a reservoir of AMR bacteria, food from farm animals represent a potential source of these microorganisms, including AMR pathogens. Bacteria have the ability to share genetic information critical for their survival in litter and animal gut. Positive associations between farm level antimicrobial use in broiler production and subsequent detection of AMR genes has been shown previously. The project intends to delineate the bacterial resistome in broilers and their environment and study its subsequent impact on the dissemination and persistence of AMR Salmonella and Campylobacter in ABR production systems.

As our publications related to this goal are produced, we will include them on this page.
