Subacute Chlamydial Endocarditis

Abstract

Chlamydial endocarditis has been infrequently reported. A case of blood-culture—negative endocarditis is described in which there was serological evidence of a<i>Chlamydia psittaci</i>infection. Chlamydiae were also identified in aortic valve vegetations by electron microscopy and immunofluorescent staining. Patients with culture-negative endocarditis should be evaluated for infection with<i>Chlamydia</i>as well as other uncommon pathogens. (<i>JAMA</i>1982;247:655-658)
