【摘要】：目的建立一種快速、準確、可視化、易開展的B、E型腺病毒檢測技術(shù)。方法針對B、E型腺病毒殼蛋白保守序列設(shè)計通用引物,建立可同時檢測出這兩種腺病毒型別的重組酶聚合酶擴增結(jié)合側(cè)流層析試紙條(recombinase polymerase amplification combined with a lateral flow dipstick,LFD-RPA)檢測技術(shù),評價其靈敏度與特異性,并驗證最佳反應(yīng)溫度與反應(yīng)時間,同時利用該法對19例B、E型腺病毒感染患者及10例健康志愿者鼻咽拭子標本進行檢測。結(jié)果腺病毒LFD-RPA法檢測靈敏度可達10拷貝/μl,與q PCR方法相近,且不會與其他亞屬腺病毒及其他病毒發(fā)生交叉反應(yīng)。反應(yīng)可在25~45℃溫度范圍內(nèi)高效進行,檢測全程僅需15~20 min。利用臨床咽拭子標本對檢測體系進行評估,其靈敏度及特異性均達100%。結(jié)論該檢測方法靈敏度高、特異性強、操作簡單,反應(yīng)快速,能脫離對大型儀器、專業(yè)操作人員及正規(guī)實驗室的依賴,在基層衛(wèi)生部門,尤其在野外及現(xiàn)場檢測中具有極大的應(yīng)用潛力。
[Abstract]:Objective to establish a rapid, accurate, visual and easy detection technique for adenovirus type E (AV). Methods A universal primer was designed for the conserved sequence of adenovirus type E adenovirus shell protein, and a recombinant enzyme polymerase amplification method combined with LFD-RPAA assay was developed to detect the two adenovirus types simultaneously. The recombinant polymerase amplification combined with side flow chromatography test strip was used to detect the recombinant adenovirus types. The sensitivity and specificity were evaluated, and the optimum reaction temperature and reaction time were verified. At the same time, the nasopharyngeal swabs of 19 patients with adenovirus type E infection and 10 healthy volunteers were detected by this method. Results the sensitivity of LFD-RPA assay was up to 10 copies / 渭 l, which was similar to that of Q PCR, and no cross reaction with other subgenus adenovirus and other viruses was observed. The reaction can be carried out efficiently in the temperature range of 25 鈩，
