在这项研究中,我们调查和比较了18个人的头发(头皮头发)和头皮上的细菌群落结构特征。显着差异的网站之间,在细胞密度,α和β多样性,以及门,厚壁菌门和变形菌门的相对丰度,而没有发现差异的门放线菌的相对丰度。细菌属Cutibacterium表现出相似的相对丰度在这两个网站,而属Pseudomonas是高度丰富的头发上,和属Staphylococcus的头发上的丰度显着低于头皮。网站之间的统计相关性很高的个人相对丰度的五个主要业务分类单位(OTUs)。这表明头发上的细菌群落结构由头发特异性属假单胞菌和皮肤衍生属皮肤细菌和葡萄球菌组成,并且与其他人类皮肤微生物组区分开来。
In this study, we investigated and compared characteristics of the bacterial community structures on hair (scalp hair) and scalp in 18 individuals. Significant differences were found between the sites, in terms of cell density, alpha and beta diversity, and relative abundance of the phyla, Firmicutes and Proteobacteria, whereas no difference was found in relative abundance of the phylum Actinobacteria. Bacteria of the genusCutibacteriumshowed similar relative abundance at both sites, whereas those of genusPseudomonaswere highly abundant on hair, and those of genusStaphylococcuswere significantly lesser in abundance on hair than on scalp. Statistical correlations between the sites were high for the individual relative abundance of five major operational taxonomic units (OTUs). This suggests that the bacterial community structure on hair is composed of hair-specific genus,Pseudomonas, and skin-derived genera,CutibacteriumandStaphylococcus, and is distinguishable from other human skin microbiomes.
