    Hello and welcome to Parasites: Trypanosoma. This is another in-depth look at parasites of human importance that happen to be protozoans. And after listening to this lecture, you'll understand the lifecycles of Trypanosoma parasites and how they’re transmitted to humans. You will be familiar with the pathogenesis of the different forms of American and African trypanosomes and you will know how to prevent and treat trypanosomiasis. So again these are all eukaryotic protozoan parasites of medical importance. We've looked at plasmodia, toxoplasma, leishmania, and now let's examine the Trypanosomes. Here's a photograph of the blood form of Trypanosoma species. These are very typical flagellated parasites, with a lovely undulating membrane on one side and you can see in this photo, this is a blood smear, so there are red blood cells present. First we will look at the African Trypanosoma. There are African and American Trypanosomes with very different outcomes. One of the African Trypanosomaes, Trypanosoma brucei gambiense. Let’s take a look at the distribution of this. You can see that these parasites are found largely in central Western Africa. Very specific place, nowhere else on the planet. Trypanosoma brucei gambiense. The other trypanosome present in Africa is Trypanosoma brucei rhodesiense. And let's take a look at the distribution of this parasite. Look it's very different, that's on the eastern coast of South Africa, very different from gambiense. These infections, these parasites, are spread by the Tsetse fly, the species glossina, these are very large flies, you can't tell from this photograph, an inch long, that can give you quite a nasty bite and deliver quite a serious disease. Among the African trypanosomiasis, the animal reservoirs are different for the East African and the West African parasites. The reservoirs for the East African parasites are game animals, like impalas, like...
