Endocarditis due to the anaerobe Peptostreptococcus

Infective endocarditis caused by anaerobic bacteria is infrequent. A case is described in which infective endocarditis was caused by the anaerobe Peptostreptococcus. A review of the literature on anaerobic endocarditis led to the conclusion that the clinical picture is identical to that of other forms of endocarditis. The need for routine culturing of blood under anaerobic conditions in patients with endocarditis is stressed.
