摘要: 根据GenBank 发表的DHV I的基因序列,设计了1对针对DHV I保守区的特异性引物。通过对反应条件的优化,建立了鸭病毒性肝炎病毒快速鉴别诊断的RT-PCR方法,扩增片段大小为632 bp。试验表明,RT-PCR法具有很强的特异性,且该方法的敏感性明显高于常规的检测方法。对鸭病毒性肝炎的病料检测证明,该方法能有效鉴别DHV,特异性良好。

Abstract: According to the conserved gene sequence of Duck Hepatitis Virus I(DHV I) in GenBank, one pair of the specific primers were designed. A rapid diagnostic technique of RT-PCR was established by optimizing the reaction condition. The DNA segments amplified were 632 bp. The experiments had proved that RT-PCR possessed a high specificity. And the sensitivity test results indicated that the RT-PCR was more sensitive than the conventional method. Detection of field samples from viral diseased ducks also confirmed that the method of RT-PCR could effectively identify the infection of DHV.

Key words: Duck Hepatitis Virus I, RT-PCR, diagnosis
