[The local specific immune response to Staphylococcus aureus protein A in human tonsillar lymphoid tissue]

Formation of antibodies and development of delayed hypersensitivity to protein A are usual components of the immune response of tonsillar lymphoid tissue to S. aureus infection in chronic tonsillitis in man. The preparations of transfer factor, produced from human tonsillar T-cells, show increased activity in the intraspecific transfer of delayed hypersensitivity to staphylococcal protein A from humans to mice.
