Diversity of the human intestinal microbial flora.

The human endogenous intestinal microflora is an essential "organ" in providing nourishment, regulating epithelial development, and instructing innate immunity; yet, surprisingly, basic features remain poorly described. We examined 13,355 prokaryotic ribosomal RNA gene sequences from multiple colonic mucosal sites and feces of healthy subjects to improve our understanding of gut microbial diver...

Intestinal Microbial Flora – Effect of Probiotics in Newborns

The surface of the human gut has a surplus area of 200-250 m2 in order to contain, between intraepithelial lymphocytes and lamina propria, Peyer’s patches and lymphoid follicles, the lymphoid tissue, while hosts a flora of about 800 different bacteria species with over 7000 strains. The 99% are obligate anaerobes and varies species were then classified using traditional anaerobic culture techni...

Effect of Genetically Modified Rice on Some Intestinal Microbial Flora in Rats

 Background and purpose: Transgenic rice is a type of rice that its genetic sequence has been changed to improve its quantity and quality. Bt (Bacillus thuringiensis) transgenic rice expresses Cry1Ab protein and is named Tarom Molaii. There are no studies on the effect of this type of transgenic rice on gastrointestinal health in Iran, so, this study investigated the effect of Tarom Molaii tran...
