A Case of Community-Acquired Pneumonia Caused by Multidrug-Resistant Acinetobacter baumannii in Korea

Acinetobacter baumannii is an aerobic Gram-negative coccobacillus that causes nosocomial pneumonia in patients on mechanical ventilation or previously treated with broad-spectrum antibiotics. Nevertheless, community-acquired pneumonia (CAP) caused by A. baumannii, especially multi-drug resistant (MDR) strains, is rare. We experienced the first case of CAP caused by MDR A. baumannii in Korea in a 78-year-old man. This case shows that MDR A. baumannii can cause CAP in Korea.
