Urban Birds Are Harboring Antibiotic-Resistant Bacteria


Exposure to bacteria in landfill sites and polluted rivers may explain prevalence among city-dwelling birds.

Urban ducks and crows might offer us a connection to nature, but scientists have found wild birds that live near humans are more likely to harbor bacteria resistant to important antibiotics. The team looked specifically at the presence of different strains of Campylobacter jejuni —a type of bacteria that are ubiquitous in birds as a natural part of their gut microbiome. “The most obvious place to start is to ensure birds do not congregate in our landfills, wastewater treatment plants, and animal muck piles, where both pathogens and AMR are abundant,” he said.
