Certain Bartonella species are known to cause afebrile bacteremia in humans and other mammals, including B. quintana, the agent of trench fever, and B. henselae, the agent of cat scratch disease. Reports have indicated that animal-associated Bartonella species may cause paucisymptomatic bacteremia and endocarditis in humans. We identified potentially zoonotic strains from 6 Bartonella species in samples from patients who had chronic, subjective symptoms and who reported tick bites. Three strains were B. henselae and 3 were from other animal-associated Bartonella spp. (B. doshiae, B. schoenbuchensis, and B. tribocorum). Genomic analysis of the isolated strains revealed differences from previously sequenced Bartonella strains. Our investigation identifed 3 novel Bartonella spp. strains with human pathogenic potential and showed that Bartonella spp. may be the cause of undifferentiated chronic illness in humans who have been bitten by ticks.



Quintessential Culture-Negative Endocarditis.

Bartonella spp are important causes of culture-negative endocarditis, generally causing a subacute insidious form of endocarditis, often leading to a delay in diagnosis. Most patients have fever and often present with signs and symptoms of heart failure. The diagnosis is frequently established only on meticulous examination of the resected heart valve with the polymerase chain reaction technique. We present a case of B quintana mitral and aortic valve endocarditis with associated severe valvular insufficiency and decompensated heart failure precipitated by Streptococcus pneumoniae bacteremia, necessitating urgent surgical valve replacement. Pathologic examination of the valve complemented by serologic and molecular testing established the surprising diagnosis of B quintana endocarditis.
