Gall bladder empyema secondary to Methicillin-resistant Staphylococcus aureus (MRSA) infection is a very rare occurrence that was scarcely reported. Methicillin-resistant Staphylococcus aureus is a bacterium that causes infections in different parts of the body. It's tougher to treat than most strains of staphylococcus aureus, or staph, because it is resistant to some commonly used antibiotics. Garden-variety staph are common bacteria that can live on our bodies. Plenty of healthy people carry staph without being infected by it. In fact, 25-30% of us have staph bacteria in our noses.
However, staph can be a problem if it manages to get into the body, often through a skin compromise. MRSA has become a major problem worldwide and is associated with significant morbidity and mortality (D.Q.A. Nguyen and N.I Ramus). Teranishi et al reported a case of acute cholecystitis caused by MRSA in the Japanese literature. No prior such cases were reported.
