Abstract: The indirect immunoflouresent antibody test (IFAT) and immunoenzymatic staining technique (IEST) with frozen sections of Brugia malayi and Setaria cervi adult worms as antigens were used to detect IgG levels in rabbits immunized with three different filarial antigens. The results showed the dynamics of the specific IgG antibody in the course of immunization. The peaks (GMRT 76.11-861.08) of feG levels in immunized rabbits appeared at the 4th week after primary immunization, which returned to (4.00-32.0 up to the 8th week after paimary immunization and rose to(20.11-181.02)at the 1st week after second immunization. It is suggested that IF AT and IEST, especially the latter, can be applied for serodiagnosis of filarial infection and both antigens are considered to be of similar diagnostic effect.
