Industrial poultry farming has played a role in the spread of Campylobacter, according to researchers.
Scientists from the Ineos Oxford Institute found that the chicken host environment may drive the evolution of strains that are more likely to cause human infections.
Campylobacter is the most common bacterial cause of diarrhea worldwide. Rising rates of antimicrobial resistance (AMR), which occurs when bacteria resist drugs designed to kill them, are making infections more difficult to treat.
