The composition and diversity of the gut microbiota are known to be different between babies and adults. The aim of this project was to compare the level of bifidobacteria between babies and adults and to investigate the influence of lifestyle factors on the level of this bacterium in the gut. During this study, the levels of bifidobacteria in 10 human babies below 2 years of age were compared with that of 10 human adults above 40 years. The level of bifidobacteria proved to be significantly higher in babies in comparison with adults. This investigation concluded that a combination of several factors, such as age, diet, and BMI, has an important effect on the level of bifidobacteria in adults, while in babies, a combination of diet and age may influence the level of intestinal bifidobacteria.
婴儿和成人的肠道微生物群落组成和多样性是不同的。本项目的目的是比较婴儿和成人双歧杆菌的水平，并研究生活方式因素对肠道中这种细菌水平的影响。在这项研究中，将 10 名年龄在 2 岁以下的人类婴儿与 10 名年龄在 40 岁以上的成人的双歧杆菌水平进行了比较。结果表明，与成人相比，婴儿的双歧杆菌水平显著更高。本研究得出的结论是，年龄、饮食和 BMI 等多种因素的组合对成人双歧杆菌水平有重要影响，而在婴儿中，饮食和年龄的组合可能会影响肠道双歧杆菌的水平。
