چکیده

The organisms of the Order Rickettsiales, in the families Rickettsiaceae and Anaplasmataceae, were reclassified in 2001 following phylogenetic analyses of the 16S rRNA and groESL gene sequences (Dumler and colleagues, 2001). Some Ehrlichia spp. were transferred to the Neorickettsia genus (including E. risticii) and some Ehrlichia spp., including E. phagocytophila (also called E. equi and human granulocytic Ehrlichia) and E. platys) were placed into the genus Anaplasma. The genera Ehrlichia and Neorickettsia were transferred to the family Anaplasmataceae; the genera of Rickettsia and Orientia remained in the Rickettsiaceae. The organisms in the Ehrlichia, Anaplasma, and Neorickettsia are classified genetically and by cell tropism (Monocytotropic, granulocytotropic, or thrombocytotropic).
