概括

选择正确的口腔样品对于微生物组研究至关重要. 口水提供了更高的细菌多样性,而唾液提供了更多的DNA用于分析.

科学领域:

微生物学微生物学
基因组学就是基因组学.
口腔健康口腔健康

背景情况:

口腔微生物组失调与炎症状况和粘膜损伤有关.
了解口腔微生物组的组成对于诊断和治疗口腔疾病至关重要.

研究的目的:

为了确定代表性人类口腔微生物组分析的最佳样本类型.
为了比较从唾液,口腔冲洗和粘膜组织中获得的微生物概况.

主要方法:

一项涉及六名健康成年人的观察性,横截面研究.
从每个参与者身上收集唾液,口腔冲洗和粘膜活检样本.
使用Illumina MiSeq技术对18个样本进行16S rRNA基因测序 (V3-V4区域).

主要成果:

与唾液和组织相比,口腔冲洗样本中的细菌α多样性明显高 (p=0.005).
唾液样本中发现的细菌物种相对丰富度最高 (56%),其次是口腔冲洗 (30%) 和组织 (1%).

结论:

根据样本类型,口腔微生物组组成存在显著差异.
在优先考虑细菌多样性的研究中,建议用口腔冲洗.
在口腔微生物组研究中,为了最大限度地提高细菌DNA产量,首选的是整个未刺激的唾液.

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains.
