title: A preliminary study on the immunodiagnosis of paragonimiasis--the physico-chemical and immunological characteristics of the crude and partially purified antigens of Paragonimus westermani (Liaoning).
abstract: We have now succeeded in preparing a partially purified antigen (Fr. 1). The positive rates of the indirect ELISA were 100% both for sera of proved human cases and dogs infected with Paragonimus westermani when Fr. 1 was used, whereas the positive rates of the test were 71.4% and 75% on sera from patients and infected dogs respectively when crude antigen was used. Moreover, it is also better than the crude antigen in specificity, so a more reliable test in immunodiagnosis of paragonimiasis is available in our laboratory.
