开发了一种基于巢式聚合酶链反应(n-PCR)检测的犬冠状病毒(CCV)感染诊断检测方法,并使用以下冠状病毒株进行了检测:CCV(USDA毒株),CCV(45/93,野毒株),猫传染性腹膜炎病毒(FIPV,田间株),传染性胃肠炎病毒(TGEV,Purdue株)、牛冠状病毒(BCV,9 WBL-77株)、传染性支气管炎病毒(IBV,M-41株)和患有CCV肠炎的犬的粪便样品。该引物的靶序列为编码CCV跨膜蛋白M的基因的230 bp片段。本研究中描述的试验能够扩增CCV和TGEV毒株,并且对CCV感染犬的粪便样品也给出阳性结果。n-PCR具有与细胞培养分离一样高的灵敏度,因此可用于诊断犬CCV感染。
A diagnostic test for canine coronavirus (CCV) infection based on a nested polymerase chain reaction (n-PCR) assay was developed and tested using the following coronavirus strains: CCV (USDA strain), CCV (45/93, field strain), feline infectious peritonitis virus (FIPV, field strain), trasmissible gastroenteritis virus (TGEV, Purdue strain), bovine coronavirus (BCV, 9WBL-77 strain), infectious bronchitis virus (IBV, M-41 strain) and fecal samples of dogs with CCV enteritis. A 230-bp segment of the gene encoding for transmembrane protein M of CCV is the target sequence of the primer. The test described in the present study was able to amplify both CCV and TGEV strains and also gave positive results on fecal samples from CCV infected dogs. n-PCR has a sensitivity as high as isolation on cell cultures, and can therefore be used for the diagnosis of CCV infection in dogs.
