Class: Alpha Proteobacteria
Order: Rickettsiales
Family: Anaplasmataceae
Genus: Ehrlichia
Species: Ehrlichia ewingii

Ehrlichia ewingii is a species of rickettsiales bacteria.

Previously known to infect dogs, it has recently been associated with human infection (see Human ewingii ehrlichiosis).[1]

There is currently no serological test.[2] PCR can be used in diagnosis.[3]

The name Ehrlichia ewingii was proposed in 1992.[4]

It is classified as a member of genus Ehrlichia.[5]

The bacteria use ticks as a vector.
