About Anaplasmosis

Anaplasmosis is a common, seasonal, non-contagious, tick-transmitted disease observed where the Ixodes tick vector is found. Horses might display acute clinical signs including lethargy, biphasic fever, and reduced appetite. These are often followed by more severe signs, including icterus, limb edema, mucous membrane petechiation, and reluctance to move. Horses usually recover over a two- to three-week period.
