[Studies on the dynamic changes in specific antibodies in sera from animals infected with unisexual and bisexual cercariae of Schistosoma japonicum].
The IEST using both liver tissue-egg frozen section of mice infected with Schistosoma japonicum and adult worm frozen section of Schistosoma japonicum (TEFS-IEST and AWFS-IEST) were performed to study the dynamics of specific antibodies in sera from rabbits infected with unisexual and bisexual cercariae of Schistosoma japonicum. Both peaks of specific antibodies appeared at the 10th week after infection. The levels of specific antibodies were much higher in bisexual infection than in unisexual infection and closely related to the intensity and duration of infection. The levels of anti-egg antibodies were higher than those of anti-adult worm antibodies. The serological reactivity of egg antigen is higher than that of adult worm antigen. TEFS-IEST shows higher sensitivity and specificity than AWFS-IEST and DGS-COPT for the diagnosis of schistosomiasis.
