This cluster analysis shows phylogenetic relationships among A. centrale and various Ehrlichia spp. based on the 16S rRNA gene sequences using program Clustal W to construct the phylogenetic tree. The scale bar represents 1% divergence. The numbers at nodes are the proportions of 1,000 bootstrap resamplings that support the topology shown.

This most excellent nucleotide sequencing is by Inokuma H, Terada Y, Kamio T, Raoult D, and Philippe Brouqui P. 2001. Analysis of the 16S rRNA gene sequence of Anaplasma centrale and Its phylogenetic relatedness to other Ehrlichiae. Clin Diagn Lab Immunol, 2001, 8: 241-244.
