||"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."
||"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."
