Anisakis simplex: stage-specific antigens recognized by mice
Published online by Cambridge University Press: 05 June 2009
Abstract
To investigate antigenic differences between the developmental stages of Anisakis simplex, somatic, excretion–secretion and detergent-solubilized surface antigen preparations of third- and fourth-stage A. simplex larvae, and a somatic antigen preparation of adults, were characterized by SDS–PAGE and immunoblotting using mouse immune serum containing antibodies against the two larval stages. Excretion–secretion and surface antigen preparations from thirdstage larvae behaved very differently from those of fourth-stage larvae, in both SDS-PAGE and immunoblotting; this suggests that certain excretion–secretion and surface antigens are highly stage-specific. By contrast, somatic components of third- and fourth-stage larvae were found to have very similar banding patterns, suggesting conservation of these components during the development of the parasite in mice. The SDS-PAGE and immunoblotting results for adult somatic components seem to support this hypothesis
