Zoonotic bartonella species in cardiac valves of healthy coyotes, California, USA

Abstract

We investigated whether Bartonella spp. could cause endocarditis in coyotes or localize to cardiac valves before lesions develop. Bartonella DNA was amplified more often from coyote cardiac valves than spleen. Bartonella infection apparently leads to cardiac valve tropism, which could cause endocarditis, an often lethal complication in mammals, including humans.
