Anaplasmosis is an infectious parasitic disease of cattle, sheep, and goats caused by the microorganism Anaplasma marginale. This parasite infects the red blood cells and causes severe anemia, weakness, fever, lack of appetite, depression, constipation, decreased milk production, jaundice, abortion, and sometimes death. The incubation time for the disease is typically around 21-45 days. Adult cattle are more susceptible to infection than calves.
