Investigation of the phylogenetic relationships within the genus Bartonella based on comparative sequence analysis of the rnpB gene, 16S rDNA and 23S rDNA.

A variety of genes and analytical methods have been applied to the study of phylogenetic relationships within the genus Bartonella, but so far the results have been inconsistent. While previous studies analysed single protein-encoding genes, we have analysed an alignment containing the sequences of three important phylogenetic markers, RNase P RNA, 16S rRNA and 23S rRNA, merged by catenation, to determine the phylogenetic relationships within the genus Bartonella. The dataset described here comprises 13 different Bartonella strains, including the seven strains that are known to be human pathogens.
