摘要: 根据GenBank 发表的鸭瘟病毒(DPV)的基因序列,设计了针对DPV UL6 UL7保守区1对特异性引物。通过对反应条件的优化,建立了鸭瘟病毒快速鉴别诊断的PCR方法,扩增片段大小为1 293 bp。试验结果表明PCR法具有很强的特异性,且敏感性较高,最低DNA模板检出量为15 pg/mL。对鸭瘟的临床病料检测证明,该方法具有特异、快速和敏感的特点,可有效鉴别DPV。

Abstract: According to the conserved gene sequences of Duck plague virus(DPV) in GenBank, one pair of specific primer was designed. A rapid diagnostic technique of PCR was established by optimizing the reaction condition. The DNA segments amplified were 1 293 bp. The experiments had proved that PCR possessed a high specificity. And the sensitivity test results indicated that PCR was more sensitive, which could detect DHV with only 15 pg·mL-1 DNA. Detection of field samples from viral diseased ducks also confirmed that the PCR method could identify the infection of DPV, which was specific, rapid and sensitive.

Key words: Duck hepatitis virus, PCR, detection
