- 微生物学 微生物学
- 基因组学就是基因组学.
- 整形外科 整形外科 整形外科
背景情况:
- 对于磁盘细菌菌群的传统培养方法是有限的,通常只专注于Cutibacterium acnes.
- 下一代测序提供了一种更全面的方法来理解磁盘微生物群落.
研究的目的:
- 为了研究正常与退化的磁盘中的细菌菌群的多样性.
- 通过使用先进的基因组工具,识别导致磁盘退化的潜在病原体.
主要方法:
- 16S元基因组测序60个磁盘样本 (20个健康,40个退化).
- 使用QIIME-2管道和Greengenes/SILVA数据库对细菌多样性的分析.
- 通过使用液体染色学-质谱学识别代谢物的细菌存在的验证.
主要成果:
