Steer with bovine trypanosomiasis Cachectic dog infested with T. congolense after travel in West Africa. Animal trypanosomiasis, also known as nagana and nagana pest, or sleeping sickness, is a disease of vertebrates. The disease is caused by trypanosomes of several species in the genus Trypanosoma such as T. brucei.
Diagnosis relies on recognition of the flagellate on a blood smear. Motile organisms may be visible in the buffy coat when a blood sample is spun down. Serological testing is also common. One common way in which trypanosomiasis can be diagnosed in humans is through the detection of antibodies against trypanosomes made by host organisms. [6]
Chagas disease, also known as American trypanosomiasis, is a tropical parasitic disease caused by Trypanosoma cruzi.It is spread mostly by insects in the subfamily Triatominae, known as "kissing bugs".
T. brucei rhodesiense which causes fast onset acute trypanosomiasis in humans. A highly zoonotic parasite, it is prevalent in southern and eastern Africa, where game animals and livestock are thought to be the primary reservoir. [45] [48] T. brucei brucei which causes animal trypanosomiasis, along with several other species of Trypanosoma. T. b.
Another large group of vectors are flies. Sandfly species transmit the disease leishmaniasis, by acting as vectors for protozoan Leishmania species, and tsetse flies transmit protozoan trypansomes (Trypanosoma brucei gambiense and Trypansoma brucei rhodesiense) which cause African Trypanosomiasis (sleeping sickness). Ticks and lice form another ...
