Allergy and Immunity in Tuberculosis

[摘要] Guinea-pigs inoculated with the dissociated human strain H37Ra developed cutaneous sensitivity which reached a peak at four to six weeks and gradually declined, tending to disappear completely twenty-eight to fifty-two weeks after infection.On reinfection with the homologous strain H37Rv animals with different degrees of cutaneous sensitivity showed no difference in the amount of protection conferred by the primary infection. Those with developing cutaneous sensitivity, peak sensitivity, waning sensitivity and zero sensitivity fared equally well in their resistance to reinfection.
