Moraxella lacunata infection associated with septicemia, endocarditis, and bilateral septic arthritis in a patient undergoing hemodialysis: a case report and review of the literature

J Infect Chemother. 2014 Jan;20(1):61-4. doi: 10.1016/j.jiac.2013.06.002. Epub 2013 Nov 12.

Abstract

We report the first case of both endocarditis and bilateral septic arthritis in a patient caused by Moraxella lacunata and successful management of the infection with antimicrobial therapy. The route of entry leading to bacteremia may have been the oral cavity given the poor oral hygiene of the patient as evidenced by bleeding gums. We hypothesize that the bacteremia led to septic arthritis and mitral valve infective endocarditis. In this case report, we also review the literature on M. lacunata infections and conclude that this organism should be considered in bilateral septic arthritis in a patient with underlying heart abnormalities and/or with renal failure.
