<i>Bartonella</i>spp. and<i>Coxiella burnetii</i>Associated with Community-Acquired, Culture-Negative Endocarditis, Brazil

Abstract

We evaluated culture-negative, community-acquired endocarditis by using indirect immunofluorescent assays and molecular analyses for Bartonella spp. and Coxiella burnetii and found a prevalence of 19.6% and 7.8%, respectively. Our findings reinforce the need to study these organisms in patients with culture-negative, community-acquired endocarditis, especially B. henselae in cat owners.
