At least 13 of the 35 currently recognized Bartonella species are pathogenic for humans. Most of the pathogenic species, except Bartonella quintana and Bartonella bacilliformis, are zoonotic agents with animal reservoirs, including cats, dogs, coyotes, foxes, cattle, and rodents. In this study, a novel Bartonella species was isolated from the blood of a Crocidura suaveolens (Pallas, 1811) Lesser shrew that was captured in the Bartln region of Northwestern Turkey. The strain, RSKK 19006, was characterized using whole-genome sequencing and comparison, multilocus sequence typing (gltA, rpoB, ssrA, nuoG, and 16S rRNA) and internal transcribed spacer sequencing, electron microscopy scanning, biochemical tests, and MALDI-TOF MS (matrix assisted laser desorption ionization-time of flight mass spectrometry). This novel Bartonella is a Gram-negative, rod-shaped, microaerophilic bacterium and has neither flagella nor pilus. As a consequence, we propose to name this new species Bartonella refiksaydamii sp. nov. in Bartonella genus. The zoonotic potential of this novel Bartonella species is as yet unknown.
