Affinoblotting analysis with lectins showed that 10 of these components were glycoproteins with different types of glycan structure. Only one immunogenic antigen was isolated using immunoaffinity chromatography with the gammaglobulin fraction of an antigen-specific antiserum as immunospecific ligand.

However, in rats the antibody activity decreased and the profile of specific antibodies, tested by immunoblotting, remained the same as before the treatment. The specific immune response in rabbits artificially immunized with whole-body Psoroptes cuniculi extract was not affected by ivermectin.

The lectins concanavalin A and wheat germ agglutinin bound strongly to the immunogen, the gut and its semidigested contents. Electrophoretic and blotting analysis showed the presence of a 31-kDa glycoprotein component reacting with specific rat antibodies, concanavalin A and wheat germ agglutinin in louse faeces. The result indicates that the 31-kDa immunogen is secreted by the midgut epithelium into the gut lumen and faeces.
