When maintained in culture, the infective-stage larvae of Toxocara canis produce a group of excretory-secretory antigens. Monoclonal antibodies to these antigens have been produced and partially characterized. Hybridomas were made using spleens from mice that had been given 250 embryonated eggs of T. canis followed by immunization with excretory-secretory antigens. Monoclonal antibodies were first screened against excretory-secretory antigens using an indirect enzyme-linked immunosorbent assay. Those antibodies positive in this assay were then screened against the surfaces of formalin-fixed, infective-stage larvae using an indirect fluorescent antibody assay. The two monoclonal antibodies showing fluorescence were also tested against the surfaces of infective-stage larvae of Toxocara cati, Baylisascaris procyonis, Toxascaris leonina, Ascaris suum, a Porrocaecum sp., and Dirofilaria immitis. One of these two antibodies bound to the surface of T. canis and T. cati while the other bound only to the surface of T. canis; neither were reactive with the other ascaridoid larvae or the larvae of D. immitis. Enzyme-linked immunoelectrotransfer blotting techniques were used to demonstrate that the cross-reactive antibody recognized antigens with molecular weights of about 200 kDa while the more specific monoclonal antibody recognized antigens with approximate molecular weights of 80 kDa. The specificity of these two antibodies for T. canis and T. cati should prove helpful in the development of more specific assays for the diagnosis of visceral and ocular larva migrans.
