Abstract

Background: Bartonella quintana is a facultative intracellular bacterium and the causative agent of trench fever. The disease was reported during the World Wars in pre-antibiotic era and is associated with louse infestation and poor hygiene conditions. Bartonella bacteraemia may result in endocarditis mostly in people with existing heart valve abnormalities.

Case Report: We report a case of endocarditis caused by B. quintana in a 77-year-old woman with previous valvulopathy. This active endocarditis case was characterized by aortic root involvement 5 years after surgical aortic valve replacement. Although the initial serological tests had induced to a presumptive diagnosis of Q fever, B. quintana infection was confirmed by PCR and sequencing. Detection of Bartonella DNA in valvular and abscess specimens was determinant to confirm Bartonella infection in the absence of other associated risk factors.

Conclusions: Bartonella infection should be considered in patients with pre-existing valvular disease and with a blood culture-negative endocarditis.
