[Cellular reactions of increased delayed sensitivity in human pseudotuberculosis].

A total of 145 patients having Far Eastern scarlatiniform fever, 99 healthy persons and 54 patients with diseases of non-pseudotuberculous etiology have been examined by means of Fradkin's neutrophil damage test, the capillary cell migration inhibition test and the intradermal test. The specific transformation of the cellular immunity system has been shown to occur in scarlatiniform fever. This transformation takes the form of delayed type hypersensitivity reaction. The immunological tests used in this study have been found to be specific, highly sensitive, simple and suitable for diagnosing Far Eastern scarlatiniform fever.
