概括
在无症状携带者中观察到Fusobacterium necrophorum的PCR Ct值较高,与患有喉感染的患者相比. 然而,这些值在预测疾病严重程度或并发症方面没有显示出临床有用性.
科学领域:
- 微生物学 微生物学
- 传染性疾病 传染性疾病
- 分子诊断学 分子诊断
背景情况:
- Fusobacterium necrophorum是一种细菌,与各种人类感染有关,包括喉炎.
- 聚合酶连锁反应 (PCR) 周期值 (Ct) 值通常用于量化病原体负载.
- 了解Ct值在F. necrophorum感染中的临床实用性对于患者管理至关重要.
研究的目的:
- 为了研究桃体Fusobacterium necrophorum PCR Ct值和临床表现之间的关联.
- 为了确定F. necrophorumCt值是否可以预测疾病严重程度或并发症的发展.
- 评估报告F. necrophorum喉样本中Ct值的临床有用性.
主要方法:
- 来自疑似或确诊感染F. necrophorum的患者的PCR数据的回顾性分析.
- 在无症状携带者和具有症状喉感染的个体之间比较CT值.
- 对Ct值和临床结果之间的相关性分析,包括疾病严重程度和并发症.
主要成果:
- 桃体F. necrophorum PCRCt值在没有症状的桃体携带的参与者中明显高于急性喉感染的参与者.
- CT值没有与喉感染的严重程度有显著的关联.
- 没有发现F. necrophorum的Ct值能够预测并发症的发展.
结论:
- 在临床样本中报告Fusobacterium necrophorum PCR Ct值不建议,因为缺乏证明的临床有用性.
- 虽然Ct值在无症状携带和活跃感染之间可能有所不同,但它们不能可靠地告知疾病预后或管理决策.
- 可能需要进一步的研究来确定F. necrophorum感染的更多临床相关的生物标志物.

01:23Chronic Pharyngitis
2.1K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

57.3K
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
