Transfer of Delayed Hypersensitivity to Coccidioidin in Man

Summary and Conclusions Generalized delayed sensitivity to coccidioidin can be transferred in human subjects with DNase-treated leukocyte extracts obtained from sensitive donors. This has been accomplished in 23 out of 27 consecutive attempts with leukocyte extracts obtained from moderately to markedly sensitive donors, and in 5 out of 8 consecutive attempts with leukocytes obtained from minimally to moderately sensitive donors.
