Lantos,corresponding author1 Ricardo G. DESIGN: The study design was a retrospective case series. The bacterial genus Bartonella is distributed worldwide and poses a public health risk []. vinsonii subsp. The most involved species in human infections are Bartonella bacilliformis, Bartonella quintana and Bartonella henselae. Due to the fastidious growth characteristics of the bacteria, the limited sensitivity of histopathological stains, and the non-specific histological findings on liver biopsy, the diagnosis of hepatic bartonellosis can be difficult to establish. Cat scratch disease (CSD) is the most frequent clinical manifestation of Bartonella infections in immunocompetent patients (8, 9, 18, 19, 23, 28). Bartonella spp. This assay can differentiate between Bartonella henselae and Bartonella quintana. Various Bartonella species are shown in Table 1. An IgG antibody titer >1/800 has a positive predictive value of 95%. In a recent article, Bergmans et al. Atypical presentations of B. berkhoffii has co-evolved with dogs and wild canines, and Bartonella bovis has co-evolved with cattle.
