Anaplasma

/Ana·plas·ma/ (-plaz´mah) a genus of microorganisms (family Anaplasmataceae), including A. margina´le, the etiologic agent of anaplasmosis.

Anaplasma

a genus of organisms in the family Anaplasmataceae, order Rickettsiales. Members parasitize erythrocytes, thrombocytes and leukocytes and are transmitted by ticks.

Anaplasma bovis
causes benign bovine rickettsiosis in Asia and Africa. Previously Ehrlichia bovis.
Anaplasma caudatum
often found in mixed infections with A. marginale in cattle.
Anaplasma centrale
causes a mild form of anaplasmosis in cattle and has been used as a vaccine against A. marginale.
Anaplasma marginale
a significant pathogen, the cause of anaplasmosis in ruminants. The infection is transmitted mechanically by many biting insects. Ticks, including Boophilus spp. and Dermacentor spp., are biological vectors.
Anaplasma ovis
the cause of anaplasmosis of sheep.
Anaplasma phagocytophilum
causes tickborne fever or 'pasture disease' in cattle, goats, sheep and wild ruminants; granulocytic ehrlichiosis in cattle, cats and llamas, both of which are characterized by leukopenia and thrombocytopenia, equine ehrlichiosis, and human granulocytic ehrlichiosis. Transmitted by Ixodes ticks. Previously Ehrlichia equi (Rickettsia phagocytophila and Rickettsia equi), E. phagocytophila and the human granulocytic ehrlichiosis (HGE) agent.
Anaplasma platys
the cause of canine infectious cyclic thrombocytopenia. The only rickettsia known to infect platelets. Thought to be transmitted by Rhipicephalus sanguineus. Previously called Ehrlichia platys.
