A single strain of bacterium appears to be responsible for almost all cases of the staph infection CA-MRSA in non-hospitalized people. The strain is hardy, say researchers, and will likely cause many more infections in the coming years.

The National Institute of Allergy and Infectious Diseases reports in its study that USA300 is an evolving bacterium, and will evolve into many derivatives.

Methicillin-resistant Staphylococcus aureus, or MRSA, cannot be treated with the most commonly used antibiotics. Doctors rely on newly developed antibiotics that can cause collateral damage to the patient.

Most cases of MRSA infection occur in hospitals. But increasingly these potentially deadly germs are making their way into the community at large.
