Anaplasma
Encyclopedia
Anaplasma is a genus of rickettsiales
bacteria
.
Anaplasmas reside in host red blood cells and lead to the disease anaplasmosis
. The disease most commonly occurs in tropical areas of the world.
Anaplasmas require intermediate tick
hosts for maturation, and flies may act as mechanical vectors.
The major consequence of infection is the development of haemolytic anaemia due to the damage done to red blood cells.
Species of veterinary interest include:
Rickettsiales
The Rickettsiales, also called rickettsias, are an order of small proteobacteria. Most of those described survive only as endosymbionts of other cells. Some are notable pathogens, including Rickettsia, which causes a variety of diseases in humans...

Anaplasmosis
Anaplasmosis is a disease caused by a rickettsial parasite of ruminants, Anaplasma spp. The organism occurs in the white blood cells and is transmitted by natural means through a number of haematophagous species of ticks...
