Control & Prevention Of Anaplasmosis
Anaplasmosis is usually thought of as a late summer and early fall problem in the Midwest, but more and more it is causing problems year around. It is caused by a tiny parasitic organism called Anaplasma marginale that invades the red blood cells. The animal’s immune system tries to deal with the problem by removing the affected red blood cells from the circulation, but in destroying the organism the red cells are also destroyed. This results in a series of symptoms associated with anemia and the characteristic yellow or orange coloration of the body tissues, which comes from pigments released as the red cells are broken down. Because anaplasmosis is a disease of mature cattle and the transmission is more efficient under range conditions, it is usually associated with beef cow herds more than feedlot or dairy animals.
