“…His wife, who butchered the rabbits, was not infected, suggesting that B. alsatica may present a tropism for patients with cardiovascular abnormalities including prosthetic grafts. This is in agreement with one of the two previously described B. alsatica endocarditis cases in which a bioprosthetic aortic valve was also infected 4…”

“…Only three cases of B. alsatica infection in humans have been reported so far, one lymphadenitis2 and two endocarditis3 cases. Although two cases of prosthetic vascular graft infection (PVGI) caused by B. henselae were previously reported,4 this is the first case of PVGI associated with B. alsatica and therefore the fourth human case of B. alsatica infection.…”

Bartonella alsatica is a wild rabbit pathogen causing bacteremia rarely reported in humans, with only three cases published so far, including one lymphadenitis and two endocarditis cases. Here, we report the case of a 66-year-old man who suffered from acute renal failure due to a membranoproliferative glomerulonephritis. Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) showed diffuse FDG uptake around the aortobifemoral graft with no indication of infection. A white blood cell scan showed an accumulation of labeled neutrophils on the left femoral part of the graft. The patient underwent surgery and an abscess around the left iliac part of the graft was found intraoperatively. Intraoperative samples were all negative, but 16S rRNA gene-based PCR was positive, and the sequence was positioned among the Bartonella species cluster. Specific PCRs targeting gro EL/ hsp 60, rpo B and glt A genes were performed and led to the identification of B. alsatica . Accordingly, indirect immunofluorescence serological analyses were positive for Bartonella henselae and Bartonella quintana . The patient had a history of regularly hunting wild rabbits. He was treated with 100 mg of doxycycline twice a day for six months and his renal function significantly improved with no sign of persistent infection. This case highlights the contribution of serology assays and molecular-based methods in prosthetic vascular graft infection diagnosis.

Culture-negative endocarditis due to Bartonella quintana

et al. 2016

Bartonella spp. was first described as a possible cause of culture-negative endocarditis in 1993, and has since emerged as a significant cause of this condition worldwide. We describe a complicated case of culture-negative endocarditis in an immune-competent male patient, which was confirmed on resected heart valves to have been caused by Bartonella quintana by broad-range 16S ribosomal RNA polymerase chain reaction. The objective of this report is to highlight the clinical, diagnostic and therapeutic challenges of Bartonella endocarditis.
