The aim of the present study was to investigate the presence of Bartonella infections in elk populations. We report the isolation of four Bartonella strains from 55 elk blood samples. Sequencing analysis demonstrated that all four strains belong to Bartonella capreoli, a bacterium that was originally described in the wild roe deer of Europe. Our finding first time demonstrated that B. capreoli has a wide geographic range, and that elk may be another host for this bacterium. Further investigations are needed to determine the impact of this bacterium on wildlife.
