摘要: 猫传染性鼻气管炎(FIR)病毒是引起猫传染性鼻气管炎的病原,属于猫疱疹病毒1型(FHV-1)。选择FHV-1gD基因设计1对引物FHV-1F、FHV-1R和探针FHV-1Probe,建立FHV-1实时荧光定量PCR检测方法。结果表明,该方法可以特异地检测出FHV-1的DNA,敏感性达到75fg/μL,反应效率达到107%,R2值为0.9965,Ct值的变异系数低于2%。FHV-1实时荧光定量PCR检测方法敏感性高于普通PCR,特异性好、稳定性好,适用于FHV-1的临床诊断、检测和流行病学调查。利用该方法对上海地区宠物门诊送检的疑似FHV-1感染的样品进行检测,其阳性率达到27.78%,表明上海地区宠物猫FHV-1的发病率处于较高水平。

Abstract: Feline herpesvirus type 1 (FHV-1) is the pathogeny of feline infectious rhinotracheitis.Based on the sequence of gD gene of FHV-1, one pair of primers(FHV-1F and FHV-1R) and FHV-1Probe were designed for the quantitative Real-time PCR detection method.The results showed that the method could detect FHV-1 DNA specifically and the sensitivity was 75 fg/μL.The reaction efficiency reached 107%, and the R2 value was 0.9965.The coefficient of variance(CV) was below 2%.And the method was more sensitive than common PCR.It was specific, stable, and suitable for clinical diagnosis, detection and epidemiological investigation.Using this method, the Shanghai area pet clinic censorship suspected FHV-1 infected samples were detected, and the positive rate reached 27.78%, which indicated that the incidence of FHV-1 in Shanghai area was at a high level.

Key words: FIR; quantitative Real-time PCR; detection
