ABSTRACT
The result regarding the application of McAbs against PwMJ-SAg in the detection of the circulating antigens(CAg) in sera from the patients (early stage and nonpulmonary type) with paragonimiasis westermani was reported in this paper. CAg in the sera from 35 patients in the early stage and 15 nonpulmonary type of patients was 100% positive by using McAb IB1 and JB4 out of 8 McAbs against PwMJ-SAg. Furthermore, these two McAbs didnot react crossly with the sera from 25 normal subjects, 15 patients with clonorchiasis, 15 patients with fasciolopsiasis, 15 patients with schistosomiasis japonica, 16 patients with Brugian filariasis or 10 patients with pulmonary tuberculosis. However, they crossly reacted with 8 samples of sera from 15 patients (53.3%) with pagumogonimiasis skrjabini. The McAb IB1 and IB4, threfore, are appropriate as the reagents to diagnose paragonimiasis westermani (early stage or nonpulmonary type). Moreover, they are also valuable, to a certain degree, to diagnose pagumogonimiasis skrjabini.The projet was supported by NNSFC Department of parasitology .Anhni Medical University, Hefei
