Superbugs Hitching Rides on Gulls

A superbug resistant to the last-line antibiotic colistin has been found in seagulls in Europe and South America—indicating one vehicle for the spread of resistant bacteria.

2 separate research teams in Lithuania and Argentina, in letters to the Journal of Antimicrobial Chemotherapy, found the resistance-conferring gene in E. coli in Lithuania’s herring gulls and Argentina’s kelp gulls.

The birds probably picked up bacteria by eating garbage containing sewage or medical waste, the researchers surmise.
