Abstract
Recent advance in the technologies to analyze the composition of bacterial communities, including pyrosequencing, has provided a much longer list of bacterial names related to human intestinal microbiota. Out of 30 phyla of the domain Bacteria and 5 phyla of the domain Archaea, 11 phyla of the domain Bacteria and 1 phylum of the domain Archaea are detected in the human intestinal tract. This paper describes the phylogenetic positions of species inhabiting the human digestive tract.
