Flies more germ-laden than suspected

Scientists have discovered that flies carry more diseases than suspected.

The house fly and the blowfly together harbour more than 600 different bacteria, according to a DNA analysis.

Many are linked with human infections, including stomach bugs, blood poisoning and pneumonia.

Flies can spread bacteria from place-to-place on their legs, feet and wings, experiments show. In fact, every step taken by a fly can transfer live bacteria, researchers said.
