Anaplasma is a genus of rickettsiales bacteria.
Anaplasmas reside in host blood cells and lead to the disease anaplasmosis. The disease most commonly occurs in tropical areas of the world.[2]
Anaplasmas require intermediate tick hosts (eg. Dermacentor ) for maturation, and flies may act as mechanical vectors.[2]
One of the major consequences of infection by red blood cells infecting Anaplasma is the development of haemolytic anaemia due to the damage done to red blood cells.[2]
Species of veterinary interest include:
- Anaplasma marginale and Anaplasma centrale in cattle
- Anaplasma mesaeterum and Anaplasma ovis in sheep and goats[2]
- Anaplasma phagocytophilum in dogs, cats and horses (see Human granulocytic anaplasmosis)
Genomes
The genomes from at least three different Anaplasma species have been sequenced.[3] These genomes are about 1.1 to 1.2 MB in size and encode 925 to 1,335 proteins.
