下一代测序揭示了整个欧洲引起支气管病变的微生物和抗菌素耐药性基因的地理变异. 这些发现凸显了因病原体和耐药性概况的区域差异而需要量身定制的抗微生物策略.
科学领域:
- 微生物学和基因组学 微生物学和基因组学
- 肺部医学 肺部医学
- 传染性疾病 传染性疾病
背景情况:
- 欧洲多中心支气管炎检查和研究合作 (EMBARC) 登记处在欧洲各国发现了唾液微生物的显著差异.
- 下一代元基因组测序的作用及其与支气管切除症中的抗菌电阻体的关联仍然未被探索.
研究的目的:
- 在EMBARC支气管炎研究涉及数据库,基因组学和内型化 (BRIDGE) 研究中使用下一代猎枪元基因组测序来前性评估吐微生物组和抗体组概况.
- 调查这些特征与临床结果的关联,并探索欧洲各地的区域差异.
主要方法:
- 展望分析了来自8个欧洲国家的349名个体的唾液样本,分为北欧/西欧,南欧和英国.
- 采用下一代猎枪元基因组测序来确定微生物组和抗体组的概况.
- 评估了与临床结果和地理区域相关的微生物和耐药性基因配置文件.
主要成果:
- 转基因组测序证实了先前观察到的国家特定的微生物特征差异,并增强了对关键支气管病原体的检测 (例如,Pseudomonas aeruginosa,Haemophilus influenzae,Streptococcus pneumoniae).
- 确定了三种主导的泛欧洲微生物群 (*Pseudomonas*, *Streptococcus*, *Haemophilus*) 具有可变的分布和与微生物群相关的多样性抵抗体.
- 在南欧观察到显著更高的耐药性多样性,具有独特的区域多药性耐药性概况和经过验证的支气管切除症耐药型 (RT1,RT2) 的区域变异.
结论:
- 甲基因组学证实并扩展了欧洲各地支气管病菌微生物学的区域变异现有的知识.
- 病原体分布和抗微生物药物耐药性基因的显著地理差异需要考虑针对特定欧洲地区量身定制的抗微生物实践.

Gram Stain
The Gram Stain is an integral part of sputum studies. It involves the staining of sputum, which permits...
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,...
