Abstract:
Bartonella quintana and Bartonella pediococcus infections are very rare causes of endocarditis. Urban trench fever with relapsing febrile illness, headache, leg pain, and endocarditis has now begun to be a more important cause of disease in socially disadvantaged persons. The diagnosis is difficult because the growth of B. quintana in blood culture takes 20-40 days. B. pediococcus may be an opportunistic pathogen in severely compromised hosts, although it has been described as a harmless bacterium. We describe a patient who developed bioprosthetic valve infection with B. quintana and B. pediococcus after valve replacement.
