A genus of bacteria (family Anaplasmataceae) that parasitize red blood cells, where they appear as spherical chromatic granules; there is no demonstrable multiplication of these organisms in other tissues. These organisms are natural parasites of ruminants (families Bovidae and Camelidae) and are transmitted by arthropods. Initially regarded as protozoa, they are now placed in the order Rickettsiales. The type species is Anaplasma marginale.
