Abstract
Antimicrobial resistance (AMR) has proven to be a global public health concern. To conquer this increasingly worrying trend, an overarching, One Health approach has been used that brings together different sectors, but the fundamental knowledge of the relationship between humans, food animals, and their environments is not mature yet or is lacking in some aspect. With swine and chicken as examples of food animals, a large global data set of over 1,000 human and food animal gut metagenomes was analyzed with a focus on acquired antibiotic resistance genes (ARGs) associated with mobile genetic elements (MGEs) to answer this question. Outputs from this work open a new avenue to further our understanding of ARG transferability in food animals. It is a necessary milestone to better equip governmental agencies to monitor and pre-empt antibiotic resistance hot spots. This work will assist and give guidance on how to decipher other links within any One Health initiatives with expected positive feedback to human health.
