Abstract

PVL-positive ψUSA300 CA-MRSA is increasingly identified in Japan and is primarily associated with skin and soft tissue infections; respiratory infections caused by this clone remain rare. We report a 49-year-old healthy woman with lung abscess and empyema caused by PVL-positive ψUSA300, successfully treated with vancomycin and linezolid. This case expands the known clinical spectrum of ψUSA300 and underscores the need for CA-MRSA consideration in otherwise healthy patients with severe pulmonary infections.
