The gut microbiome of healthy Japanese and its microbial and functional uniqueness

Abstract: The human gut microbiome has profound influences on the host's health largely through its interference with various intestinal functions. As recent studies have suggested diversity in the human gut microbiome among human populations, it will be interesting to analyse how gut microbiome is correlated with geographical, cultural, and traditional differences. The Japanese people are known to have several characteristic features such as eating a variety of traditional foods and exhibiting a low BMI and long life s… Show more

“…Conversely, our results showed no relationship between the major energy source and bacterial abundance for any bacterial group. Determination of gut microbiota based on the 16S rRNA gene analysis method showed a greater abundance of Bifidobacterium in Japanese subjects than in subjects from other countries, especially those from the USA, China, and Korea, who showed a relatively low abundance (,2%) of Bifidobacterium (42,47). Likewise, our data showed a high abundance of Bifidobacterium in all of our Japanese subjects (average approximately 12%).…”

“…he genus Bifidobacterium represents one of the major components of the intestinal microbiota of breastfed infants (1)(2)(3)(4)(5) while also typically constituting between 2% and 10% of the adult intestinal microbiota (6)(7)(8)(9)(10)(11). Bifidobacteria are saccharolytic microorganisms whose ability to colonize and survive in the large intestine is presumed to depend on the ability to metabolize complex carbohydrates present in this environment (12,13).…”
