Cryptosporidium, like Plasmodium falciparum or Toxoplasma gondii, is an apicomplexan parasite that infects both humans and animals. Phylogenetic analyses indicate that the phylum Apicomplexa shares a common ancestor with ciliates and dinoflagellates, which form the clade Alveolata (Ellis et al. 1998 Fig. 10.2).
