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.[1]

Anaplasmas require intermediate tick hosts (eg. Dermacentor ) for maturation, and flies may act as mechanical vectors.[1]

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.[1]

Species of veterinary interest include:


The genomes from at least three different Anaplasma species have been sequenced.[2] These genomes are about 1.1 to 1.2 MB in size and encode 925 to 1,335 proteins.
