Nematospiroides dubius: influence of adjuvants on immunity in mice vaccinated with antigens isolated by affinity chromatography from adult worms.

Abstract:

:Five adjuvants were examined for their ability to potentiate the immune response of mice to soluble antigens from adult Nematospiroides dubius prepared by affinity chromatography against antibodies from repeatedly infected mice as ligands (IMIgAg). Immunized mice were better protected against N. dubius by IMIgAg injected intraperitoneally with either pertussigen (75%) or aluminium hydroxide (Alum) (67%) as adjuvants than with Freud's complete (54%) or incomplete adjuvants (31%). Protection was correlated with elevated specific antibody values and with cellular responses. Quil A was toxic to recipient mice at the concentration used. Alum may be a more practical adjuvant than pertussigen, which may activate protective immunity only in specific recipient genotypes and oil-based adjuvants which appear to be less efficient, to vaccinate mice with soluble parasite antigens.
