title: [Acute Neisseria subflava endocarditis].
abstract: A 50-year-old woman who developed acute endocarditis on a mitral Starr valve due to Neisseria subflava is reported. This microorganism, which belongs to the normal flora of the upper respiratory tract, is a very rare cause of endocarditis since only 9 cases have been described. The patient developed various complications including right hemiplegia. Cure was obtained by medical therapy alone due to the high susceptibility of the bacteria to a third generation cephalosporin (moxalactam). This is the third time a neurological complication of this kind is reported during N. subflava endocarditis. A high frequency of neurological and systemic embolic complications appears to be an important feature of endocarditis due to N. subflava and other saprophytic Neisseria.
