这项研究引入了一种使用混合原料进行下一代测序 (NGS) 的新方法,以同时分析直管患者中的细菌和真菌群体. 这种方法有助于了解诸如呼吸机相关肺炎和Candida等感染.
科学领域:
- 微生物学 微生物学
- 基因组学就是基因组学.
- 传染性疾病 传染性疾病
背景情况:
- 在重症监护室 (ICU) 的输管患者容易患有呼吸器相关的肺炎和Candida感染.
- 口腔道微生物被认为是这些感染的重要病因因素.
研究的目的:
- 评估下一代测序 (NGS) 的有效性,用于同时分析细菌和真菌群落.
- 开发一种新的方法,用于在被直管患者中进行全面的微生物组分析.
主要方法:
- 从被直管的ICU患者中采集了口腔样本.
- 使用了针对细菌16S rRNA (V1-V2区域) 和真菌18S rRNA (ITS2区域) 的原始剂.
- 混合的V1-V2/ITS2原料被用于准备NGS库进行同时分析.
主要成果:
- 使用混合V1-V2/ITS2原料实现了同时确定细菌和真菌的丰度.
- 经过NGS和RT-PCR调整后的相对丰度显示,在与标准微生物群体进行调整后,相关性很高.
- 这项研究揭示了口腔大微生物组中的新型跨王国和内部相互作用.
结论:
- 混合的V1-V2/ITS2原始剂可以同时检测细菌和真菌群落.
- 这种新的NGS方法可促进对两个王国的微生物群落进行全面分析.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
