RESUMO
Guinea pigs sensitized with washed, Formalin-killed cells of Staphylococcus aureus, strains 263 or Copenhagen, were skin-tested with various antigens from these strains including washed viable and heat-killed whole cells, cell walls, the peptidoglycan complexes of the walls, teichoic acid, teichoic acid-peptidoglycan fragments, and peptidoglycan fragments. In nonsensitized control animals, all antigens but teichoic acid elicited acute inflammatory reactions which decreased in size after 10 hr. In animals sensitized with the Copenhagen strain, the reactions to all antigens but teichoic acid and peptidoglycan fragments from either strain remained erythematous and indurated for at least 30 hr and were interpreted as hypersensitivity of the delayed type. Responses in animals sensitized with strain 263 generally resembled those in controls, although in some experiments there was evidence of hypersensitivity.
