Urban birds are teeming with antibiotic-resistant bacteria, study finds

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 harbour bacteria resistant to important antibiotics.

Antimicrobial resistance (AMR) is largely caused by the overuse of drugs such as antibiotics among humans and livestock.
