Abstract: Rotavirus is one of the main pathogenic microorganisms threatening the survival of giant pandas. In order to detect panda rotavirus antigens quickly, conveniently and accurately, it is necessary to develop a detection method suitable for ex-situ breeding centers and protection areas. In this study, the panda rotavirus Vp7 gene sequence was synthesized to construct the PUC-VP7 recombinant plasmid, and it was used as a positive control for PCR detection and analysis of panda rotavirus samples. The results showed that during the PCR amplification analysis, both the plasmid and the viral cDNA showed a specific band at 340 bp. In addition, when performing rotavirus antigen detection on forty-five panda rotavirus fecal samples, two samples showed a band at 340 bp, and the gene fragment was 99.89% homologous to the panda rotavirus CH-1 strain. The PUC-VP7 plasmid constructed in this study can not only be used as a positive quality control material in the PCR detection of giant panda rotavirus, but can also effectively improve the promotion and application of the PCR virus detection technology in ex-situ breeding centers and protected areas.

摘要: 轮状病毒是威胁大熊猫健康的主要病原微生物之一。为了对大熊猫轮状病毒进行快速、方便且准确地检测,研发适合于基层饲养单位和保护区的检测方法是非常有必要的。本研究通过合成大熊猫轮状病毒Vp7基因序列,构建了PUC-VP7的重组质粒,并将其作为阳性对照对大熊猫轮状病毒样本进行PCR检测和分析。结果表明,在进行PCR扩增分析时,该质粒和病毒cDNA二者均在340 bp处出现了特异性条带。此外,对收集到的45份大熊猫粪便样本进行轮状病毒抗原检测时,其中2份样品在340 bp处出现条带,该基因片段与大熊猫轮状病毒CH-1株的相似性为99.89%。本研究构建的PUC-VP7质粒不但可以作为大熊猫轮状病毒PCR检测中的阳性质控品,而且还能有效地促进该PCR病毒检测技术在基层饲养单位和保护区的推广和应用。
