Notes:

• This phylogram are constructed based on 16S rRNA sequences of these species. Nomenclature are changed from their original names based on 16S rRNA sequences which divided them into four genera groups.
• Family Anaplasmataceae now contains four genas: Ehrlichia, Anaplasma, Neorickettsia, and Wolbachia.
• Please read previous section (General Characteristics of Ehrlichia) and next section (New Taxonomy of the Family Anaplasmataceae) for more details.
