摘要: 根据GenBank中H6、N1亚型禽流感病毒(AIV)的HA、NA基因序列,设计2对特异性引物和2条用不同荧光基团标记的TaqMan探针.经反应条件优化,本试验建立了检测H6N1亚型AIV的二重荧光RT-PCR方法.该法特异性强,只对H6亚型和N1亚型AIV进行特异性扩增,对其他H亚型AIV、N亚型AIV及新城疫病毒、传染性支气管炎病毒等病原体的检测均为阴性;该法敏感性好,对H6N1亚型AIV的检测限为100拷贝/μL.本试验建立的H6N1亚型AIV的二重荧光RT-PCR方法,具有快速、敏感、特异的优点,为H6N1亚型AIV的防控提供技术支撑.

Abstract: According to the sequences of HA and NA genes of H6 and N1 subtype avian influenza virus (AIV),two pairs of specific primers and two TaqMan probes with different fluorescence were designed.The duplex Real-time RT-PCR assay was developed and optimized to simultaneously detect H6 and N1 subtypes AIV in one reaction.The result showed that the specificity of this assay was high and only amplified H6 and N1 subtypes AIV,and was not cross-reactive with other H and N subtypes AIV,newcastle disease virus and infectious bronchitis virus.The detection limit of this assay was 100 copies/μL of H6N1 subtype AIV.This newly developed duplex Real-time RT-PCR assay was a rapid,specific and sensitive method for the detection of H6N1 subtype AIV,and it could provid a technical support to prevent and control H6N1 subtype AIV.

Key words: avian influenza virus; H6N1 subtype; duplex Real-time RT-PCR
