The sporozoan group of protists is also known as Apicomplexa. Some well-known members include:

* Plasmodium: The parasite responsible for malaria.

* Toxoplasma gondii: Causes toxoplasmosis, a disease that can be dangerous to pregnant women and people with weakened immune systems.

* Cryptosporidium: A parasite that causes cryptosporidiosis, a diarrheal illness.

* Babesia: A parasite that causes babesiosis, a tick-borne disease.

* Eimeria: Parasites that cause coccidiosis in animals, leading to intestinal problems.

So, to answer your question, any of these (or others in the Apicomplexa group) would be a valid answer.
