Liver and spleen abscesses without endocarditis due to Bartonella quintana in an immunocompetent host

The spectrum of Bartonella quintana infections is expanding constantly. The first cases of bacteremia were described in 1915 under the name of trench fever, but more recently B. quintana has been related with bacillary angiomatosis [1]. In the 1990s new forms of B. quintana bacteremia, which were different from historical trench fever, were described in both immunocompetent and immunocompromised patients (mostly homeless people with body lice or with chronic alcoholism) under the name of urban trench fever [2]. Bartonella quintana has also been reported as an agent of bacterial endocarditis in HIVpositive or homeless patients [3]. We report here a case of liver and spleen abscesses due to B. quintana not associated with endocarditis, homelessness or immunodepression.
