Probable Bartonella clarridgeiae Prosthetic Valve Endocarditis and Aortic Root Abscess, Australia, 2020.

We describe a case of endocarditis and aortic root abscess caused by Bartonella clarridgeiae bacteria in a patient in Australia. The patient initially sought care for leg pain and was found to have bilateral tibioperoneal trunk mycotic aneurysms. 16S rRNA PCR on excised aneurysm tissue identified the cause as B. clarridgeiae.
