[Detection of the localization of C1. botulinum antigens in regional lymph node cells by the immunofluorescence technic].

As a result of the study of lacalization of the C1. botulinum toxoids of the A, B, and E types in cells of the regional lymph nodes of rabbits by the indirect Coons' method and by the smear-print method it was revealed that different types of lymphoid tissue cells took part in the ingestion and digestion of these antigens; the antigens of the A and B types were at first revealed in the cytoplasm of pseudoeosinophils, and then in the macrophages. The antigen of the E type was revealed in the course of the whole experiment in the macro phages of the regional lymph node, although the number of pseudoeosinophils also increased. Apparently there was a different activity of pseudoeosinophils against the C1. botulinum toxoids, the types A, B and E.
