Beta-lactamase genes in bacteria from food animals, retail meat, and human surveillance programs in the United States from 2002 to 2021
This study investigates the distribution of beta-lactamase genes in three US sampling sources: cecal, retail meat, and human. 115 genes were detected in E. coli, Salmonella enterica, Campylobacter, Shigella, and Vibrio. The proportions of beta-lactamase genes varied between bacteria. The study provides insights into the molecular epidemiology of clinically important beta-lactamases in food animals and humans, allowing for better understanding of the spread of these bacteria in one health interface.
