Life Cycle

C. parvum has a complex, multistage life cycle, consisting of both asexual and sexual stages within one host.[4-6] The complete cycle is intracellular within epithelial cells. Infection is initiated through ingestion of the sporulated oocyst. Within the small intestine of the host, the oocyst ruptures releasing four sporozoites. Sporozoites rapidly penetrate the plasma membrane of epithelial cells lining the gut and undergo a series of cycles of asexual replication. The eventual production of sexual forms of the parasite leads to the development of sporulated oocysts. Two forms of oocysts are produced. Thick-walled oocysts are hardy, withstanding harsh environmental factors until ingested by a new host. Thin-walled oocysts can rupture within the host, leading to autoinfection.[4'6]

Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
