Bacteria of the genus Bartonella are fastidious, Gram-negative and aerobic bacilli. Recently, Bartonella spp. seroprevalence is pretty high more than 30% in HIV positive patients, blood donors or injecting drug users in west countries. Throughout the climate changes, the increasing vector positive rate increasing the infectious risk in human. Therefore, the purpose of this study will try to understand the evolution situation in this one of the famous zoonotic agent Bartonella spp in Taiwan This study used systematic review and downloaded the Bartonella spp. sequences from different host in the GenBank. Phylogenetic analysis of gltA gene was approached for understanding the evolution relationship among host. The bootstrap value represented in 1000 for branch robustness statistical examination.

The Neighbor-joining tree of 53 gltA sequences with 245 bps length presented 9 clusters with mixed host species. Taiwan animals Common bent-wing bat and Grey shrew represented 2 monophyletic clades in this phylodynamic analysis. Tracing their origin were back to 69.39(6.58~781.17) and 94.64(5.69~1109.55) years respectively.

These works will help a lot for the zoonotic disease control, treatment and prevention systems and especially for the vaccine development.
