Abstract
Delayed type hypersensitivity against staphylococcal antigens could be induced in guinea pigs by injecting the animals with a staphylococcal homogenate in Freund’s adjuvant in all four foot pads and the nuchal skin. Maximal skin reactivity, tested intracutaneously, was observed 21 days after sensitization. Highest stimulation of lymph node cells and peripheral blood lymphocytes was also obtained 21 days after sensitization. When comparing cell walls, cell materials (nonsoluble material obtained after the separation of the cell wall fraction) and soluble fraction (obtained after sedimentation of all nonsoluble material, the strongest skin test reactions occurred after testing intracutaneously with the cell wall fraction.
