汉族和藏族婴儿肠道微生物群落结构和多样性分析(英文)
发布时间:2021-08-24 05:04
为了解民族因素对婴儿的影响,对中国汉族和藏族母乳喂养的健康婴儿粪便微生物菌群进行研究。通过16SrRNA高通量测序技术,发现两组粪便微生物的组成存在差异。在门水平上,汉族婴儿的放线菌门相对丰度较高,而藏族则以厚壁菌门为主,且两组间的厚壁菌门差异显著(P<0.05)。基于UniFrac的非加权和加权的主坐标分析表明汉族和藏族婴儿肠道微生物群结构有显著性差异。此外,偏最小二乘判别分析显示两组间微生物明显分离。研究表明,肠道微生物群可以在不同民族的婴儿之间进行区别,从而扩展人类及其共生肠道微生物群共同进化的认识。
