Individu imonokompeten dapat mengontrol dan mengeliminasi infeksi sehingga diare yang ditimbulkan dapat sembuh dengan sendirinya. Sementara itu, individu yang memiliki defek imunitas selular, sering mengalami diare kronis atau peresisten.dan kemungkinan ekstraintestinal seperti saluran empedu. Infeksi oleh parasit ini di kontrol oleh sistem imun alami dan didapat terutama imunitas yang diperantarai oleh sel. Kata kunci : Cryptosporidium sp, sistem imun alamiah, sistem imun didapat Abstract The Cryptosporidium sp. is Coccidia parasite which infects a variety of vertebrate hosts’ intestinal epithelial cells. It is the causative agent of cryptosporidiosis. The immunocompetent individual could control and eliminate the infection. Therefore the diarrhea could be cured itself.
