喉是比唾液更好的样本地点用于喉微生物组分析. 口取样对患者来说具有成本效益和舒适性,提供与直接喉取样相似的见解.
科学领域:
- 微生物学 微生物学
- 基因组学就是基因组学.
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
背景情况:
- 人类微生物组对健康和疾病至关重要.
- 与口腔腔相比,喉微生物组的作用还没有得到充分研究.
- 喉取样是侵入性的,这促使人们研究替代方法.
研究的目的:
- 为了比较微生物的多样性和组成在唾液,口腔和喉.
- 为了确定喉微生物组研究的最佳,不那么侵入性采样地点.
- 为了评估口腔作为喉微生物组诊断的替代品.
主要方法:
- 一项针对19名接受耳鼻喉外科手术的个体的前性队列研究.
- 采集了匹配的唾液,口腔喉和喉抽样.
- 进行了16S rRNA基因测序 (V3/V4区域) 和生物信息分析.
主要成果:
- 在这三个地点之间没有观察到总体分类学多样性的显著差异.
- 在唾液,口腔喉和喉中共享了13个核心类型.
- 差异丰度测试在多次比较校正后没有显示出任何显著差异.
结论:
- 口腔大与喉共享的核心分类比唾液更多,并且缺乏独特的核心分类.
- 口腔取样本是喉微生物组诊断的可行,经济有效和舒适的替代方案.
- 这一发现可以优化临床采样策略,而不会影响诊断准确度.

Sputum Studies II: Culture and Sensitivity
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,...
