Abstract

Bartonella massiliensis sp. nov., strain OS09T (= CSURB624T = DSM 23169), is the type strain of Bartonella massiliensis sp. nov., a new species within the genus Bartonella. It was isolated from a soft tick, Ornithodoros sonrai, vector of recurrent fever collected from Senegalese domestic rodent burrows. This strain is an aerobic, rod-shaped and Gram-negative bacterium. On the basis of taxonogenomic approach, we propose the creation of Bartonella massiliensis sp. nov.

Keywords: Bartonella massiliensissp. nov.; Ornithodoros sonrai; genome; senegal; soft tick.

Phylogenetic tree showing position of Bartonella massiliensis sp. nov., strain OS09T, Relative to other phylogenetically close neighbours. Sequences were aligned by ClustalW parameters within MEGA7 software. Evolutionary history was inferred using minimum evolution method. Respective GenBank accession numbers for 16S rRNA genes are indicated in parentheses. Numbers at nodes are percentages of bootstrap values obtained by repeating analysis 1000 times to generate majority consensus tree. Scale bar indicates 5% nucleotide sequence divergence.
