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,
