Cryptosporidium parvum (C. parvum) is a parasite which is found in many animals, including mice and humans. The parasite causes gastroenteritis in people with normal immunity, but can cause death in people with impaired immunity. Mice can be made immunodeficient by treating them with cortisone. Within 45 days, they became infected with parasite C. parvum, followed by the development of massive adenocarcinoma of the intestine. The cancers are found in the stomach and the ileo-cecal region at the end of the small intestine.

In this study, the goal was to determine how many oocysts** of C. parvum would be needed to infect a mouse and cause cancer. Some mice were given only 1 oocyst; others were given from 10 to 100,000 oocysts. All mice developed parasitic infections followed by adenocarcinoma. Even mice which received 1 oocyst developed cancer within 45 days in the stomach or the intestine. The cancers were seen only in animals with evidence for parasitic infection.

CONCLUSION: The study confirmed the severe infectivity of C. parvum and the relationship between parasites and cancer. The authors point out that this relationship in mice could also exist in humans, when they are severely immune-compromised.

NOTE: *Dr. Hulda Clark, Canadian naturopath, wrote “The Cure for All Cancers,” about the relationship between parasites and cancer in 1993. Her books have been treated with a great deal of skepticism by the medical community. But, eventually, she has been shown to be correct in some of her ideas. She believed that the abundant isopropyl alcohol in our environments and bodies enables the dissolving of the tough capsule of the oocyst.

There has long been documentation of the relationship between cancer and parasites. There has, also, been a close relationship between liver flukes and liver cancer. There have been documented cases of parasites being found in the middle of breast tumors.

**Oocyst is a highly protected stage of the life cycle of a parasite, and is the form which is introduced into the human gastrointestinal tract. The organism is surrounded by a protective capsule that must be dissolved for the parasite to infect the host.
