Anaplasma marginale is the most prevalent tick-borne pathogen of cattle. It is transmitted by ixodid ticks. Symptoms of acute disease are anemia, weight loss, and often death. A.marginale establishes life-long persistent infection in animals that survive disease. These animals are clinically healthy but serve as reservoirs for transmission of the pathogen.
