Cytophilic immunoglobulins on the surface of neutrophilic granulocytes in mice perorally immunized with a live vaccine made from the supressor revertant S. typhimurium Rev 8]

The reaction of the spleen cell migration inhibition in the presence of monospecific antisera against mouse G, A and M immunoglobulins was used to detect cytophilic antibodies on the surface of mouse granulocytes. The oral administration of ACR live vaccine from suppressor revertant Salmonella typhimurium Rev. 8 protected the mice against infection induced by virulent species of mouse. Salmonella typhimurium. The immunized mice showed an increase in cytophilic IgG on the surface of neutrophile granulocytes.
