Polar bear poo helps in superbug hunt

Image
Bacteria such as methicillin-resistant staphylococcus aureus (MRSA) are a growing problem in hospitals and researchers are anxious to understand how they evolve.

Norwegian researchers said they had found little sign of such microbes in the feces of polar bears in the remote Arctic, suggesting the spread of resistance genes seen in the droppings of other animals may be due to human influence.

In contrast to the results from polar bears on the Svalbard archipelago, antibiotic resistance has been discovered in a range of animals including deer, foxes, pigs, dogs and cats that live close to humans.
