Characteristics of the organisms and their antigens the tsetse fly -transmitted trypanosomes cause sleeping sickness in humans and a related disease, nagana, in domestic animals in africa. These flagellated protozoan parasites multiply largely in the blood of the mammalian host but may invade extravascular sites (lymphatics, connective tissue, central nervous system), depending on the species of trypanosome.
Trypanosome, any member of a genus (trypanosoma) of parasitic zooflagellate protozoans belonging to the order kinetoplastida. Adult trypanosomes are mainly blood parasites of vertebrates, especially fishes, birds, and mammals. Most species require an intermediate host (often an insect or a leech).
Tsetse flies are found in africa, living in damp areas along the banks of rivers and lakes. They are the size of a large housefly and feed only on blood.
