The list of types of Ehrlichiosis mentioned in various sources includes:
The ehrlichioses represent a group of clinically similar, yet epidemiologically and etiologically distinct, diseases caused by Ehrlichia chaffeensis, E. ewingii, and a bacterium extremely similar or identical to E. phagocytophila. (Source: excerpt from Ehrlichiosis: DVRD)
Human ehrlichiosis due to Ehrlichia chaffeensis was first described in 1987. The disease occurs primarily in the southeastern and south central regions of the country and is primarily transmitted by the lone star tick, Amblyomma americanum.
Human granulocytic ehrlichiosis (HGE) represents the second recognized ehrlichial infection of humans in the United States, and was first described in 1994. The name for the species that causes HGE has not been formally proposed, but this species is closely related or identical to the veterinary pathogens Ehrlichia equi and Ehrlichia phagocytophila. HGE is transmitted by the blacklegged tick (Ixodes scapularis) and the western blacklegged tick (Ixodes pacificus) in the United States.
Ehrlichia ewingii is the most recently recognized human pathogen. Disease caused by E. ewingii has been limited to a few patients in Missouri, Oklahoma, and Tennessee, most of whom have had underlying immunosuppression. The full extent of the geographic range of this species, its vectors, and its role in human disease is currently under investigation. (Source: excerpt from Ehrlichiosis: DVRD)
