抗Sj14-3-3特异性IgY的制备及其诊断日本血吸虫病循环抗原的价值
Preparation of specific yolk immunoglobulin (IgY) of Anti-Sj14-3-3 in serological diagnosis of Schistosomiasis japonica
摘要
Abstract
Objective To detect the diagnostic value of using yolk immunoglobulin ( IgY ) and establishing sandwich ELISA in Schistosoma japonicum. Methods IgY and IgG antibodies were prepared and purified from the yolk and the sera of rabbits immunized with rSj4-3-3. Double antibody sandwich ELISA using the specific IgG for capture and IgY for detection was set up to test sera of 72 cases of acute and 128 cases of chronic schistosomiasis. 132 sera of normal individuals were used as control. Additionally, 42 patients with paragonimiasis, 60 with clonorchiasis and 46 with hookworm infections were subjected to cross-reaction investigation. Results The positive rates of acute and chronics schistosomiasis were 73. 6% and 48. 4% when IgY was used as detection antibody. The negative rate of normal human sera was 94. 7% ; the cross-reactions with paragonimiasis , clonorchiasis, and hookworm infections were found to be 7. 1% , 6. 7% , and 6. 5% , respectively. Conclusion IgY based double antibody sandwich ELISA used for the detection of circulating antigens has a potential and practical value in the diagnosis of schistosomiasis.关键词
