Ehrlichia

(er-lik'ē-ă),
A genus of small, often pleomorphic, coccoid to ellipsoidal, nonmotile, gram-negative bacteria (order Rickettsiales) that occur either singly or in compact inclusions in circulating mammalian leukocytes; species are the etiologic agents of ehrlichiosis and are transmitted by ticks. The type species is Ehrlichia canis.

Ehrlichia

/Ehr·lich·ia/ (ār-lik´e-ah) a genus of the tribe Ehrlichieae transmitted by ticks and causing disease in dogs, cattle, sheep, horses, and humans, including the species E. ca´nis, E. chaffeen´sis, E. e´qui, and E. sennet´su.

Ehrlichia

a genus of small spherical to ellipsoidal, nonmotile gram-negative bacteria. They occur singly or in compact inclusions in circulating mammalian leukocytes. Some species are the causative agents of ehrlichiosis and are transmitted by ticks. Two human tick-borne diseases have been associated with Ehrlichia species: human monocytic ehrlichiosis caused by E. chaffeensis, and human granulocytic ehrlichiosis caused by E. equi.

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.
