An enterotype is a classification of gut flora. It is based on the ecosystem in the human intestinal system. The classification is done by identifying the bacteria and protists which live there. This is called the "human gut biome".
Research shows there are three distinct ecosystems in the guts of people. 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.

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.".
