Infective endocarditis due to Citrobacter koseri in an immunocompetent adult

A Dzeing-Ella et al. J Clin Microbiol. 2009 Dec.

Abstract

Citrobacter koseri (formerly Citrobacter diversus) is a motile gram-negative bacillus usually arising from urinary and gastrointestinal tracts. C. koseri rarely causes infection in immunocompetent patients and, thus far, has been considered an opportunistic pathogen. We report on a 30-year-old man, with no medical past, hospitalized for infective aortic endocarditis due to C. koseri. Four weeks of antibiotherapy led to a full recovery for this patient. However, this case is unusual, as previous history and 1 year of follow-up showed no features of intercurrent immunosuppression. Microbiological diagnosis was based on using 16S rRNA gene sequencing.
