【摘要】:針對豬傳染性胃腸炎病毒(TGEV)S基因的保守序列設計引物,以TEGV疫苗毒株為模板,克隆S基因,并構建重組陽性質粒,優(yōu)化反應體系和擴增條件,建立基于SYBR GreenⅠ染料的實時熒光定量PCR檢測方法,并對其特異性、重復性和靈敏度進行分析。結果顯示:建立的檢測方法靈敏度可達10拷貝/μL,標準曲線線性關系良好(r=0.997),擴增效率高,具有良好的特異性和重復性。使用該方法對124份臨床疑似TGEV病料進行檢測,陽性樣本有17份,檢測樣本的陽性率為13.7%。該方法可用于獸醫(yī)臨床上TGEV的快速檢測和流行病學分析。
[Abstract]:According to the conserved sequence of (TGEV) S gene of porcine transmissible gastroenteritis virus, the S gene was cloned by using TEGV vaccine strain as template, and the recombinant positive plasmid was constructed to optimize the reaction system and amplification conditions. A real-time fluorescent quantitative PCR method based on SYBR Green 鈪,
