Endocarditis due to Neisseria mucosa: two case reports and review

Abstract

Two cases of endocarditis caused by Neisseria mucosa are reported, and the literature on N. mucosa endocarditis is reviewed. N. mucosa is a rare but serious cause of endocarditis that is associated with a high rate of embolic complications and high mortality and is not always highly sensitive to benzylpenicillin. Most patients with N. mucosa endocarditis have been treated with combined therapy with penicillin and an aminoglycoside, although the optimal regimen has not been defined.
