Cell biology of trypanosomes

Dr Sue Vaughan

My laboratory is interested in the cell biology of the African trypanosome Trypanosoma brucei. This eukaryotic organism is spread by the tsetse fly and is of medical and veterinary importance as it causes sleeping sickness in Humans and Nagana in cattle in sub-saharan Africa. We are particularly interested in aspects of cell morphogenesis and how the cytoskeleton duplicates and segregates during cell division. Trypanosoma brucei is now widely regarded as a good model organism to study the biogenesis of eukaryotic cilia and flagella and we are interested how the single flagellum of this parasite divides.

See the World Health Organisation website for more information on African trypanosomes.
