The most likely, but still unproven, explanation involves the anti-inflammatory properties of both statins and aspirin,...

Outbreak of skin infections sheds light on risk factors for bacterial resistance

... is a common bacterium found on human nasal mucous membranes and skin, and strains that are resistant to methicillin can cause disease. Until recently drug-resistant strains were considered to be acquired almost exclusively in hospital settings, but reports of MRSA acquired in the community are increasing, and...
