| 摘 要： | 目的建立猪细小病毒血清学检测方法。方法用抗猪细小病毒的猪源性血清,通过IFA和IEA两种方法,首先将阳性血清吸附PK-15细胞抗原,以排除非特异反应,通过对阳性血清及3种二抗(其中IFA以FITC标记的抗猪IgG抗体,IEA分别以HRP标记的抗猪IgG抗体和SPA-HRP作为二抗)进行浓度梯度滴定,确定最佳工作浓度,并比较三种反应体系的敏感性。结果IFA最高能检测出PPV-猪组织混合感染PK-15细胞模型中1个TCID50,而其它两种反应体系均只能检测100个TCID50。结论间接免疫荧光检测方法比其它两种方法敏感性更高。

| Abstract: | ObjectiveTo establish the serological method for detection of porcine parvovirus(PPV).MethodsFirstly,the swine serum containing the antibodies against PPV was absorbed by the PK-15 to eliminate nonspecific reaction,next,the optimal reaction was determined by concentration gradient titration of the serum and the second reaction-antibodies,and then,the sensitivity among the reaction systems was compared.Results 1 TCID_50 could be acquired with IFA,however,only 100 TCID_50 could be acquired with the other two methods. ConclusionIFA method was more sensitive than the other two methods. |
