This transient depression has already been observed in some of infectious diseases as well as in viral vaccine in human, but not in R. tsutsugamushi infection. In this case of R. tsutsugamushi infection the intradermal skin test became normal after 40 days of proper therapy for this infection. In immunological analysis of lymphocytes in peripheral blood OKT3 and OKT4 decreased and OKIal increased, while lymphocyte proliferation test using PHA, concanavalin A (ConA) and pokeweed mitogen (PWM) was almost normal and suppression of immunoglobulins in serum was not detected. Although the microorganism of R. tsutsugamushi were not isolated, the diagnosis was done from the clinical symptoms and laboratory data. However, the mechanism of this transient depression of delayed-type hypersensitivity (DTH) is not yet well known., 熱帯医学 Tropical medicine 28(2). p115-122, 1986}, pages = {115--122}, title = {遅延型皮膚反応の低下を伴ったつつがむし病の一症例}, volume = {28}, year = {1986} }
