A. bovis[1] A. caudatum[1] A. centrale[1] A. marginale[1] A. ovis[1] A. phagocytophilum[1] A. platys[1] Anaplasma is a genus of gram-negative bacteria of the alphaproteobacterial order Rickettsiales, family Anaplasmataceae.

Anaplasma species reside in host blood cells and lead to the disease anaplasmosis.

[2] One of the major consequences of infection of bovine red blood cells by A. marginale is the development of nonhaemolytic anaemia, thus the absence of hemoglobinuria, which allows clinical differentiation from another major tick-borne disease, bovine babesiosis, caused by Babesia bigemina.

Infection of his red blood cells led to a severe deterioration of his health and required his hospitalization.

Molecular typing showed that Anaplasma sparouinense is distinct to all known species and more genetically related to recently described Anaplasma species causing infections in rainforest wild fauna of Brazil.
