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.
