title: Endocarditis caused by Rochalimaea quintana in a patient infected with human immunodeficiency virus.
abstract: Rochalimaea quintana and Rochalimaea henselae are closely related, fastidious, gram-negative rickettsiae. Thus far, the spectrum of human Rochalimaea sp. infections has not included endocarditis. We describe a 50-year-old human immunodeficiency virus-positive man who developed endocarditis caused by R. quintana. DNA relatedness studies, which compared our patient's blood culture isolate with known Rochalimaea species, identified the organism as R. quintana. Our report expands the spectrum of Rochalimaea sp. infections and identifies a new infectious cause of endocarditis.
