Phylogenetic position of Bartonella vinsonii subsp. arupensis based on 16S rDNA and gltA gene sequences

The nucleotide sequences of the genes encoding 16S rRNA and citrate synthase (gltA) from a recently described member of the genus Bartonella, Bartonella vinsonii subsp. arupensis, isolated from mice and from the blood of a patient suffering from bacteraemia, were determined and compared with sequences of the 16S rDNA and gltA genes of other members of the genus Bartonella in order to determine its relative phylogenetic position. B. vinsonii subsp. arupensis appeared to be closely related to B. vinsonii subsp. vinsonii, another rodent-associated taxon, and to B. vinsonii subsp. berkhoffii, which was described recently in dogs.
