Protozoal pathogens trick the immune system; the life cycle of a protist or fungal pathogen is tricky to learn; infections by eukaryotic pathogens are tricky to treat and raising funds for vaccine development is tricky to accomplish! It should be clear from your review of the learning materials in this module that this theme of multiplicity is apt for eukaryotic microbes!

In this discussion you apply what you have learned in the readings and, together with your classmates, are given the opportunity to examine diseases caused by eukaryotic microbes in more detail.

Please respond to the following:

Vaccine development for diseases caused by protists (e.g. malaria, Chagas' disease) has been much less successful than for bacterial or viral diseases. Discuss at least one biological AND one geopolitical reason for this fact.
