Protozoal Diseases of Livestock

Diseases of farm animals caused by single-celled parasites, called protozoa, that live in the gut, blood or tissues. A disease belongs here when its cited article names a protozoan such as Eimeria or Trypanosoma as the cause. Some are spread through droppings in crowded housing and damp bedding, while others are carried between animals by biting flies, so each follows the conditions that favour its route of spread. Control combines hygiene, drugs given in feed or by injection, management of vectors such as tsetse flies and, for some, vaccines or breeding for tolerance. This heading gathers them so a visitor can compare their hosts and how each is controlled.
