Intensive poultry farming helps Campylobacter spread between bird species
Intensive poultry farming has changed how Campylobacter jejuni moves among chickens and wild birds, according to an analysis of 2,747 genomes. The researchers estimate a roughly 100-fold rise in chicken-to-wild-bird transfers since 1900 and found that chicken-adapted strains often carry genes linked to antimicrobial resistance and survival in chickens.
