Various rat strains differ in the severity of lousiness. Host grooming is an important factor in the rat-louse relationship. After longlasting infestations rats become partially resistant. Serum antibody level depends mainly on the severity and the duration of the infestation, and follows the dynamics of louse population. Serum antibodies have no direct negative effect on lice.

In immunoblotting, the antisera from rats infested with the louse P. spinulosa specifically recognized from 7 to 11 antigenic components of louse whole-body homogenates. 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. Further electrophoretic and immunochemical analyses revealed that it was a glycoprotein with relative molecular weight (RMW) 31 kDa and with high mannose type of oligosaccharide.
