Reference Suau A et al., Direct analysis of genes encoding 16S rRNA from complex communities reveals many novel molecular species within the human gut. Appl Environ Microbiol. 1999 Nov65(11):4799-807. p.4799 right column top paragraphPubMed ID10543789
Method "In order to derive a detailed phylogenetic inventory of the human gut flora, [researchers] have analyzed 284 cloned bacterial 16S rDNAs extracted from a fecal sample of a healthy 40-year-old male."
Comments "This method has facilitated access to both cultivated and noncultivated microorganisms. Comparative sequence analysis revealed that only 24% of molecular species corresponded to known organisms, indicating that the vast majority of the dominant organisms of the human gut flora have so far eluded scientific description."
