Babesia bigemina is a type of protozoan parasite. In cattle, it causes babesiosis, also called “Texas fever”.
Babesiosis is a malaria-like parasitic disease caused by infection. Babesia is thought to be the second-most common blood parasite of mammals, and they can have a major impact on health of domestic animals in areas without severe winters. In cattle the disease is known as Texas cattle fever, redwater, or piroplasmosis.
