Scientists found a new form of deadly superbugs in people and dairy cows. The so-called MRSA strain cannot be detected with standard tests.
The methicillin-resistant Staphylococcus aureus is expected to pass on from dairy cattle to humans, but it cannot be passed on through dairy products.
The MRSA strain is resistant to drugs.
The new superbug makes up as little as 1 percent of MRSA causes. "More likely it´s been around in the environment for a long time, and it´s just getting into the human population," microbiologist David Coleman said.
