Wild birds are more likely to be carriers of antibiotic-resistant bacteria if they live close to humans, scientists have discovered, marking the latest warning about the global spread of “superbugs”.
Urban-dwelling species such as ducks, crows, gulls and geese had up to three times as many genetic markers associated with drug resistance as their avian counterparts from more remote places, researchers said.
The findings underscore the growing threat of anti-microbial resistance (AMR) to the effectiveness of vital medicines. They further illuminate concerns about the possible transmission of so-called zoonotic diseases between animals and humans, such as in the current bird flu outbreak in the US.
