| Outline of Final Research Achievements |
The gut microbiota of 17 patients of Alzheimer's disease were compared to that of 17 persons as a healthy control. The gut microbiota of Alzheimer's disease was different from that of healthy control by UniFrac analysis. For the reason, the decrease of the phylum Bacteroidetes in microbiota of the Alzheimer's disease patients was confirmed in comparison with healthy persons. Germ-free mice (C57BL/6) were orally administrated the feces of one Alzheimer's patient. The cognitive ability of the gnotobiotic mice due to the gut microbiota (feces) of the Alzheimer's disease patient was decreased.
