概括

人体肠道细菌的组成因性别和年龄而异,但不是体重. 组合数据分析 (CoDA) 在健康成年人中确定了与性别和年龄相关的特定细菌属,突出了其在微生物组研究中的实用性.

科学领域:

微生物组研究的研究.
人的肠道微生物群.
组成数据分析 (CoDA)

背景情况:

了解人类肠道细菌的多样性对健康至关重要.
性,年龄和体重等因素可以影响微生物组成.
之前的研究已经通过不同的方法来探索这些关联.

研究的目的:

调查西班牙队列中宿主因素 (性别,年龄,体重) 和便细菌多样性之间的关系.
评估组合数据分析 (CoDA) 分析人类微生物群数据的有效性.
识别特定的细菌种群及其与性别和年龄相关的丰度模式.

主要方法:

来自西班牙安达卢西亚的39名健康志愿者提供了便样本.
高通量测序 (16S rRNA基因V3-V4区域) 使用Illumina MiSeq.进行.
组合数据分析 (CoDA) 工具 (ALDEx2,coda4microbiome) 用于分析细菌的丰富性和多样性.
使用Phyloseq R包进行序列处理和属级别分配.

主要成果:

便细菌的α多样性没有受到性别,年龄或体重的显著影响.
组合数据分析揭示了性别和特定细菌属 (例如,*Desulfovibrio*, *Senegalimassilia*, *Negatibacillus*) 之间的显著关联.
年龄与*Streptococcus*和*Tyzzerella*等属有暂时的关联,而体重对肠道微生物组合的影响有限.
鉴定出了细菌特征平衡,可以高准确度地预测性别,而不依赖年龄和体重.

结论:

组合数据分析 (CoDA) 是探索人类微生物群数据和识别宿主-微生物关联的强大工具.
特定的肠道细菌组成与健康成年人的性别以及年龄有关.
在这个队列中,肠道微生物组与体重的关系与性别和年龄相比显得不那么明显.

关键词:
