The kinetics of antibody response to intraperitoneal infection of mice with third stage larvae of Anisakis simplex was investigated by ELISA. Maximum antibody response to excretion-secretion (ES) antigens was reached before maximum response to somatic (SA) antigens. Total immunoglobulin (Ig) production (consisting mainly of IgM and IgG1 isotypes) was very similar in both cases. Immunoblotting was used to characterize the antigens recognized by the host in the presence or absence of the metabolic products released by the parasite in vivo. Sera from mice infected with live larvae (anti-L3 L serum) and immunized with dead larvae (anti-L3 D serum) recognized a similar pattern of bands in immunoblots of ES and SA antigen preparations. In the latter, however, three bands at 14, 17 and 18 kD were only recognized by the anti-L3 L serum. A possible explanation is that these low molecular weight antigens are ES products released only in vivo. Finally, the immune response in mouse was compared using ELISA and immunoblotting with the response of a human anisakiasis reference serum, and was found to display considerable similarities. This suggests that the mouse may be a useful model for studying the immunobiology of A. simplex in man.

D003429	Cross Reactions	Serological reactions in which an antiserum against one antigen reacts with a non-identical but closely related antigen.	Cross Reaction,Reaction, Cross,Reactions, Cross
D004591	Electrophoresis, Polyacrylamide Gel	Electrophoresis in which a polyacrylamide gel is used as the diffusion medium.	Polyacrylamide Gel Electrophoresis,SDS-PAGE,Sodium Dodecyl Sulfate-PAGE,Gel Electrophoresis, Polyacrylamide,SDS PAGE,Sodium Dodecyl Sulfate PAGE,Sodium Dodecyl Sulfate-PAGEs
D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
