With the new conception of considering human as a super-organism, it is also interesting to estimate the number of genes in this human super-organism.\\n\\nPRINCIPAL FINDINGS: We presented our estimation of gene numbers in the human gut bacterial community, the largest microbial community inside the human super-organism. We got 552,700 unique genes from 202 complete human gut bacteria genomes. Then, a novel gene counting model was built to check the total number of genes by combining culture-independent sequence data and those complete genomes. 16S rRNAs were used to construct a three-level tree and different counting methods were introduced for the three levels: strain-to-species, species-to-genus, and genus-and-up. The model estimates that the total number of genes is about 9,000,000 after those with identity percentage of 97% or up were merged.\\n\\nCONCLUSION: By combining completed genomes currently available and culture-independent sequencing data, we built a model to estimate the number of genes in human gut bacterial community. The total number of genes is estimated to be about 9 million. Although this number is huge, we believe it is underestimated. This is an initial step to tackle this gene counting problem for the human super-organism. It will still be an open problem in the near future. The list of genomes used in this paper can be found in the supplementary table.", "link"=>"http://www.mendeley.com/research/more-9000000-unique-genes-human-gut-bacterial-community-estimating-gene-numbers-inside-human-body", "reader_count"=>86, "reader_count_by_academic_status"=>{"Professor > Associate Professor"=>4, "Librarian"=>1, "Researcher"=>22, "Student > Doctoral Student"=>5, "Student > Ph.
