Nice article Loretta. Kerry makes an interesting point re: symbiotic relationships between the host immune system and the intestinal flora (and fauna). The mammalian intestine is just like any other ecosystem, an there is compelling evidence that reducing the diversity of such ecosystems (for example by excessive sanitation, antibiotic use, worming drugs) can have an impact on the development of a normal immune system.
I would not necessarily advocate live worms as a mainstream therapy. However these proof of principle trials are necessary for understanding how natural products from worms may be novel anti-inflammatory drugs, similar to the recent successes with compounds from other creatures (gila monsters, vipers, cone snails, sponges).
