Phylum:  Apicomplexa, which includes Toxoplasma and Cyclospora.

 

Approximately 97% of crypto cases are caused by C. parvum, which is usually separated into two distinct genotypes with separate transmission cycles and epidemiological consequences.  Infection with genotype 1 has been associated with increased quantity and duration of oocyst shedding.  All Cryptosporidium species have been found in immunocompetent and immunocompromised people.
