Amoebas, such as Entamoeba histolytica, can cause dysentery after ingestion of contaminated water or food. Dinoflagellates are responsible for red tide and harmful algal blooms, while apicomplexans (such as Plasmodium) cause malaria. Ciliates do not typically cause dysentery, and water molds (such as Phytophthora) affect plants rather than humans.
