AbstractPatients with community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) pneumonia have poor clinical outcomes and high frequency of mortality, especially in patents with postinfluenza infection. Herein, we report a case of community-acquired pneumonia with multiple organ failure in a 51-year-old patient with initial presentation of flu-like symptoms. The influenza rapid test from the specimen of nasopharyngeal swab was positive for type B influenza virus and was confirmed by real-time polymerase chain reaction. Gram stain of bronchoalveolar lavage fluid revealed gram positive cocci in group. Both sputum and blood culture yielded MRSA. We identified the CA-MRSA was staphylococcal cassette chromosome mec type IV strain carried Panton-Valentine leukocidin gene. The patient made a complete recovery following an 8-week treatment course of linezolid and was discharged with independent daily activity. According to our experience, linezolid may be a reasonable treatment choice for CA-MRSA pneumonia due to the virulence of exotoxins.Copyright © 2019 Southern Society for Clinical Investigation.
