Summary
Single-celled eukaryotes such as Plasmodium and Trypanosoma that cause malaria and sleeping sickness.
In depth
Plasmodium (malaria) infects liver and red cells, with about 600,000 deaths a year. Trypanosoma brucei (sleeping sickness) is carried by tsetse flies and evades the immune system by changing surface proteins. Giardia and Entamoeba cause gut disease.
Parasite life cycles involve vectors and multiple stages. Drug resistance is a problem (chloroquine in malaria). Vaccines are in development.
Common mistake: malaria is caused by a protist, not a bacterium or virus.
