I found the article “Good for the Gut” interesting because I was aware of individuals purposely infecting themselves with parasites such as tapeworms for aesthetic reasons, but never heard of such a symbiotic relationship for medical reasons. The subject of P’ng Loke’s study suffered from ulcerative colitis and would intentionally infect himself with hundreds to thousands of whipworm eggs and allow them to burrow in his intestinal tract. Within months, the pain and inflammation from his ulcers would subside, but over time as the worms were evacuated, symptoms would resume. It turns out, the worms’ presence in the body caused immune cells to produce more mucus than regular, which in turn provided a barrier between E.coli and other beneficial bacteria in the stomach, keeping them from stimulating inflammation of the tract. Further tests have been done in which patients with similar autoimmune diseases ingested worms, where an overwhelming 72.4% showed improvement. What was once thought to be a parasitic relationship has become a symbiotic one in special circumstances such as these. Despite the disturbing nature of this treatment, it may very well prove to be a promising and available form of therapy in the future.
