Delayed hypersensitivity to tuberculin and other antigens in a hospital population

  • RS Walls


Delayed hypersensitivity is a valuable index of cellular immune function, provided that the incidence of positive readions in the population is known. One hundred and sixty-two hospital patients were examined, using tuberculin (PPD), streptokinase and antigens derived from Candida albicans and mumps. Whereas 75% of the group responded to Candida, 61,2% to mumps and 69,3% to streptokinase, only 30,8% showed positive Mantoux reactions. Elderly patients showed fewer reactions, but these were of similar size.
