Ehrlichia

a genus of bacteria in the family Anaplasmataceae, order Rickettsiales, recently reclassified so that some species are now Anaplasma and some as Neorickettsia. All are intracellular parasites of leukocytes and endothelial cells of animals or humans and require a vector for transmission. See also Rickettsia, Anaplasma, Neorickettsia.
