|Etymology:||Genus name: named after the German bacteriologist Paul Ehrlich (1854-1915).|
Species epithet: of ruminants.
|Significance:||The disease occurs in Africa and the Caribbean, where it causes serious problems in the livestock sector.
[Of minor importance]
|Alternative Species Name(s):||Cowdria ruminantium|
|Macromorphology (smell):||Cannot be cultivated on cell free substrates (e.g. agar plates).|
|Micromorphology:||Coccoid to elipsoid cells (about 0,5 µm i diameter), which are nonmotile. A morula can be up to 4 µm in diameter.|
|Gram +/Gram -:||G-|
|Fermentation of carbohydrates:||Is not used for identification of Ehrlichia spp. Furthermore, many intracellular bacteria lack enzymes for carbohydrate metabolism because of evolutionary gene reduction.|
|Vector:||Tick (Amblyomma variegatum and A. cajennensis).|
|Disease:||Heartwater or cowdriosis.
|Hosts:||Cattle, sheep, goats and other ruminants.|
|16S rRNA Seq.:|
||Seven species have been described within the genus Ehrlichia, which is most closely related to the genus Anaplasma.|
|Comment:||Strictly intracellular and grows in inclusions (morulae) in monocytes. Morula refers to the mulberry-like structure (Morus= mulberry in Latin) of the inclusions .|
