Symbiosis and Human Health

It seems as though the science community is starting to explore the symbiotic side to human health and well being. In an article in the New York Times there is a report about research which is looking at the effect different gut microfauna have on ones ability to extract calories from food, suggesting that this could contribute to obesity in some cases. More information can be found at Obetech, LLC. Another article in the same vein (found here) has even more bizarre implications, suggesting that parasites may effect human behavior on a large scale.
