Microbes in the Gut

JAMA. 2011;305(21):2162. doi:10.1001/jama.2011.722

The microbial constituents of an individual's gut can be classified into 1 of 3 groups or “enterotypes,” reports an international team of researchers (Arumugam M et al. Nature. doi:10.1038/nature09944 [published online ahead of print April 20, 2011]).

The enterotypes, named Bacteroides, Prevotella, and Ruminococcus, are unlikely to be affected by nutritional habits and may help explain why individuals respond differently to various drugs and diets, the researchers said.
