[Immune phenomena in experimental syngamosis. 1. Antigenic structure of Syngamus trachea].
The soluble somatic antigens of Syngamus trachea were studied by gel electrophoresis and by immunoelectrophoresis, including staining for enzyme activity. Rabbit antiserum prepared by repeated injections of parasite material was used to demonstrate the antigens. Serum obtained after 12-15 weekly injections produced up to 16 precipitation arcs with the S. trachea preparation. Two of the arcs represented reactions against contaminating host material, and enzyme activity was detected in seven arcs. Cross reactions occurred with extracts of Trichinella spiralis (two arcs) and Ascaris lumbricoides (one arc).
