Bartonella chomelii sp. nov., isolated from French domestic cattle (Bos taurus).

Two strains of bacteria isolated from the blood of French domestic cows were found to be similar to Bartonella species on the basis of phenotypic characteristics. Genotypic analysis based on sequence comparison of the 16S rRNA and citrate synthase (gltA) genes and on DNA-DNA hybridization showed that the two isolates represent a distinct and new species of Bartonella. Moreover, the phylogenetic analysis inferred from comparison of 16S rRNA and gltA sequences demonstrated that the new Bartonella species is related to other ruminant-derived Bartonella species.
