ABSTRACT
In this paper, Paraffin and Frozen sections of cysticercus cellulosae cysts were used as antigens in IFA for diagnosis of cysticercosis. The results showed that the positive rates of 92 sera and 51 sera from the patients with cysticercosis that had been confirmed were 90% and 94%. respectively, Both of them have no significant difference This shows that both the paraffin and Frozen section have the same sensitivity. The former also has the advantages of convenience in production, and there is no need for low temperature equipment. When using the two section antigens, there were cross reactivity between the sera from patients of cysticercosis and the sera from patients of hydatidosis and clonorchiasis, while the tested 30 sera from healthy persons were negative reaction.
