Summary: Apicomplexan parasites such as Eimeria, Neospora, Toxoplasma and Plasmodium are single celled organisms - protozoa - that cause some of the most serious infectious diseases of livestock and humans ever known. Transmission of these parasites is dependent on their ability to encase themselves in protective structures known as oocyst or cyst walls. These walls are resistant to harsh environmental conditions, chemicals and attack by the immune system. We will discover and characterise the molecular basis for cyst wall formation. This fundamental knowledge will be the building block for new, highly specific drugs and vaccines to control these extremely important pathogens.
