Abstract

Acinetobacter baumannii has become an important pathogen that causes healthcare-associated infections, including pneumonia, bacteremia, and urinary tract infection. Only sporadic cases of infective endocarditis (IE) have been reported worldwide, and in particular, community-acquired IE caused by A. baumannii is very rare. To our knowledge, no case has ever been reported in Korea. We report a 30-year-old woman who recovered from native-valve community-acquired IE caused by A. baumannii. She did not have any underlying diseases and presented with left-sided weakness, dysarthria, and fever. On investigation of acute cerebral infarction, a vegetation on her anterior mitral leaflet was found in echocardiography, and A. baumannii was cultured from the blood. In this case, A. baumannii showed intermediate resistance to cefotaxime and was sensitive to all other antibiotics. She underwent antibiotic therapy with cefoperazone/sulbactam for 5 weeks, without surgery. Consequently, the vegetation was absent in follow-up echocardiography, and no complications related to IE developed.
