鹦鹉热衣原体是一种人畜共患的病原体,会导致鸟类全身消耗性疾病和哺乳动物(包括人类)的非典型肺炎,构成公共卫生风险。快速诊断测定将有利于现场筛查鹦鹉热衣原体。在这项研究中,我们开发了一种基于探针的重组酶聚合酶扩增(RPA)测定法,用于快速检测鹦鹉热衣原体。设计了针对外膜蛋白A基因保守区域的特异性引物对和探针,并将其应用于实时实时RPA检测。该测试可以使用便携式设备在 39°C 下进行 20 分钟,每次反应的灵敏度接近 100 个 DNA 分子拷贝,且不与其他病原体发生交叉反应。 RPA 检测的临床性能在鹦鹉热鹦鹉热爆发中进行了评估,并且在现场应用中具有很高的准确度。流行的鹦鹉热衣原体菌株被分为 2 种基因型:A 和 C。总的来说,这项研究为在实验室环境和现场环境中筛查鹦鹉热衣原体提供了一种有前途的方法,并且 RPA 可用作监测家禽种群爆发的有效临床测试。
Chlamydia psittaci is a zoonotic agent of systemic wasting disease in birds and atypical pneumonia in mammalians including humans, constituting a public health risk. A rapid diagnostic assay would be beneficial in screening C. psittaci in the field. In this study, we developed a probe-based recombinase polymerase amplification (RPA) assay for the rapid detection of C. psittaci. The specific primer pairs and probe targeting the conserved region of the outer membrane protein A gene were designed and applied to the real-time real-time RPA assay. The test can be performed at 39°C for 20 min using a portable device, with sensitivities approaching 100 copies of DNA molecules per reaction, with no cross-reaction with other pathogens. The clinical performance of the RPA assay was evaluated in an outbreak of C. psittaci and has high accuracy levels in field applications. The epidemic C. psittaci strains were classed into 2 genotypes: A and C. Collectively, this study offers a promising approach in screening for C. psittaci both in a laboratory setting and in field settings, and RPA can be used as an effective clinical test to monitor outbreaks in domestic fowl populations.
