Gut bacteria: Each species may need its own kind.

Last week, scientists reported on a 5-year study of all the bacteria

that inhabit the human body - 100 trillion of them. This week, an

interesting article published in the journal Cell points to just how

crucial the correct bacteria may be for developing a robust immune

system....

The authors’ conclusion: “That mammalian hosts have coevolved with a

specific consortium of bacterial species that stimulates intestinal

immune maturation.â€

Finally, the authors say their study puts a new twist on the hygiene

hypothesis -- the idea that underexposure to germs while growing up

raises the risk for autoimmune disesases. The new twist is that you have

to be exposed to microbes of the /right type/ for your species.

“Heavy processing of food, frequent treatment with antibiotics and

advances in hygiene in industrialized countries may have reduced the

stability and transfer of host microbes promoting health,†they write.

Here’s an interesting video <http://youtu.be/zPO8-M_rcUo>

explaining the study featuring senior author Dennis Kasper of Harvard

Medical School.

And if you look at the right side of the Web page featuring

the research paper <http://www.cell.com/fulltext/S0092-8674%2812%2900629-0>

you can listen to an interview with Kasper. Look for the yellow button

called " PaperClip. "
