What are the histological features of Apicomplexa infections?
Histological examination of infected tissues often reveals the presence of the parasitophorous vacuole containing the parasite. For instance, in malaria, Plasmodium species can be seen within red blood cells. In toxoplasmosis, Toxoplasma gondii can form tissue cysts, particularly in the brain and muscle tissues. Cryptosporidium infections typically involve the epithelial cells of the gastrointestinal tract.
