摘要
根据C亚型禽肺炎病毒F基因序列,设计了一对针对C亚型禽肺炎病毒的特异性引物,应用该引物建立了SYBR GreenⅠ实时荧光定量RT-PCR检测C亚型禽肺炎病毒的方法,并对建立的方法进行特异性、敏感性测定和临床样品检验。经检验该方法能特异性地鉴别检测禽肺炎病毒,特异性好;敏感性可检测到10个拷贝的禽肺炎病毒质粒DNA模板;对收集的54份鸡肺病料样品进行检测,没有检测到C亚型禽肺炎病毒阳性病料。建立的SYBR GreenⅠ实时荧光定量RT-PCR方法检测C亚型禽肺炎病毒具有特异、敏感、快速、定量等优点,用该方法检测证实,采集的临床样品中还没有C亚型禽肺炎病毒的存在。
A SYBR Green Ⅰ real-time RT-PCR was developed and applied to detect avian pneumovirus subtype C.A pair of specific primers were designed and synthesized according to the fusion gene of avian pneumovirus subtype C in GenBank.The reaction parameters,such as the concentration of primers,and the reaction buffer,were optimized to develop a SYBR Green Ⅰ real-time RT-PCR for the rapid detection of avian pneumovirus subtype C.The sensitivity and specificity were tested by this method.The results in-dicated that only avian pneumovirus strain had the positive curve in this assay.As limit as 10 copies of plas-mid DNA isolated from competent cells that transferred avian pneumovirus gene was detected in this test. 54 of clinical samples collected from chicken lungs and trachea were detected by this method.It showed that all of clinical samples were negative for avian pneumovirus subtype C.It indicated that this SYBR Green Ⅰ real-time RT-PCR was a good method for detection of avian pneumovirus.It was a quick,sensi-tive,specific and quantitative method for identification of avian pneumovirus in chickens in the future.
