Abstract

Acinetobacter baumannii is an opportunistic bacterial pathogen predominantly associated with hospital-acquired infections. Here we present a case of infective endocarditis of native Mitral and Aorta valves caused by A. baumannii in a 73-year-old man. He underwent surgical excision and Pathologic specimen showed A. baumannii growth after 48 hours that was exten- sively drug-resistant (XDR). He was treated with colistin and tigecycline. Finally, he discharged with no important compli- cation. To our best knowledge, it is the first case of Acinetobacter endocarditis has ever been reported in Iran. Although XDR A. baumannii is a life-threatening pathogen, proper and timely treatment can be life-saving.
