摘要
用犬瘟热(CD)弱毒和自制的高免犬血清,建立了检测犬瘟热病毒(CDV)抗体的中和(SN)试验、间接荧光抗体技术(IFAT)和间接免疫酶染色法。这3种方法对38份CD弱毒疫苗免疫犬血清抗体效价的测定结果表明,当被检血清稀释度为1∶100时,SN试验、IFAT和间接免疫酶染色法测定时的阳性血清数分别为29,7和31份,IFAT和间接免疫酶染色法测定结果相对于SN试验结果的符合率分别为42.1%和94.7%。同时发现,当SN试验测定的血清效价在1∶100以上时,IFAT测定结果总是在1∶25以上,间接免疫酶染色法测定结果总是在1∶100以上。3种方法以各自初步确定的CDV血清抗体效价完全保护值指标计算所测血清的完全保护率,SN试验为76.3%,IFAT为78.9%,间接免疫酶染色法为81.6%。据此认为,IFAT和间接免疫酶染色法均可部分代替SN试验用于CD疫苗免疫效果的评价。
Thirty eight serum samples from dogs vaccinated with attenuated caine distemper virus (CDV) were detected by serum neutralization (SN) assay, indirect immunofluorescence antibody technique (IFAT) and immunohistochemical technique, respectively. It was found that the positive serum samples were 29 in SN assay, 7 in IFAT and 31 in immunohistochemical technique when the sera were detected at 1∶100 dilution. The statistical analysis indicated that there were 42.1% agreement between IFAT and SN assay, and 94.7% agreement between immunohistochemical technique and SN assay.
