An enterotype is a classification of living organisms. It is based on the ecosystem that is created in the human intestinal system by the bacteria that exists there. This is called the "human gut microbiome". Peer Bork and scientists that worked with him said in the April 2011 issue of Nature that they have found three enterotypes.[1][2] They think that people can be classified into one of three groups based on the bacteria in their intestines. The enterotype of each person is set while the person is an infant. The enterotype affects how well a person can digest food or absorb drugs.[3] Chimpanzees have enterotypes that look similar to human enterotypes.[4]

Type 1 has high levels of Bacteroides. Prevotella are common in Type 2. Type 3 has high levels of Ruminococcus.[1][5][6]

By combining 22 newly sequenced faecal metagenomes of individuals from four countries with previously published data sets, here we identify three robust clusters (referred to as enterotypes hereafter) that are not nation or continent specific.".
