Abstract

Antibody changes in experimental anisakiasis were observed in 10 rabbits which were infected each with 10 Anisakis simplex larvae. The sera were collected before and on the 6th to the 95th day after the infection. Using crude saline extract of Anisakis larvae as antigen, specific IgM and IgG antibody levels were observed by ELISA and SDS-polyacrylamide gel electrophoresis/immunoblot. Levels of specific-IgM antibody were elevated from the 6th day, reached their peaks on the 11th day after the infection, and dropped thereafter. Serum levels of IgG antibody increased from the 6th day and reached their peak on the 26th day after the infection, and decreased gradually thereafter. When SDS-PAGE of the crude extract was done, at least forty-one SDS-polypeptide bands were recognized. Of them, IgM antibody reacted mainly to the bands of 168, 95, 74, 64, 51, 47 and 34 kDa while IgG antibody reacted strongly to 168, 92, 85, 64, 58, 52, 42 and 40 kDa bands. The crude extract showed negligible cross reactions with sera of other parasitic diseases and normal control.
