摘要:

为比较ELISA与IFA用于检测J亚型禽白血病病毒上的差别,将5个不同梯度TCID50的NX0101病毒接种到DF-1细胞上,维持培养6个不同时间段(1、2、3、5、7和9 d),比较2种方法检测结果的相关性。试验发现接种剂量高于101.625个TCID50时,维持培养2~3 d IFA即可检出阳性结果,而ELISA检测P27抗原相对滞后2~4 d;当接种剂量低于100.625个TCID50时,维持培养至7 d IFA检测结果为阳性而ELISA检测仍为阴性。由此得出结论IFA 能快速、准确地检测到病毒的感染,而ELISA检出时间有明显滞后性。

Abstract:

For comparing ELISA and IFA in the detection of J subgroup avian leukosis virus, five different dilution of NX0101 TCID50 virus were inoculated to DF1 cell and cultured. In six different stages (1, 2, 3, 5, 7 and 9 days culturation), ELISA was applied to detect P27 antigen within supernatant and IFA was conducted to detect the infected cells respectively. Using more than 101.625TCID50 of the inoculation dose, IFA achieves identification of all the infected cells at 2 days and 3 days post inoculation, but the results from ELISA is relatively lag of 2-4 days for confirmation. Inoculating less than 101.625TCID50 of virus, IFA detect successfully the infected cells while ELISA still not detect by 7th day. The results suggest that IFA is more accurate and effective than commercial ELISA kit, ELISA have obvious hysteresis in comparison to IFA.
