title: [Studies on dynamic of antibodies detected in sera from jirds infected with Brugia malayi before and after treatment].
abstract: Indirect immunofluorescent antibody test (IFAT) and immunoenzymatic staining technique (IEST), using frozen section of Brugia malayi and Setaria cervi adult worms, were applied to detect levels of IgG and IgM antibodies in jirds infected with Brugia malayi before and after treatment. Both methods could show the dynamic of antibodies during the course of infection. The peak of IgG and IgM antibodies were at the 12-14th week and 2-6th week after infection respectively. A high correlation was observed between the levels of IgG antibody and the period of infection, whereas the antibody titer had no relation with the density of infection. During 6 months after treatment, the levels of antibodies detected by IFAT and IEST using two antigens decreased to low titre. It is considered that IFAT and IEST using heterologous and homologous antigens could be equally used for the serodiagnosis and the evaluation of cure in filariasis.
