|Abstract:||Interferon (IFN)-γ plays an important role in the induction of a type 1 immune response against intracellular pathogens. We compared the plasma levels of IFN-γ and IFN-γ-inducing cytokines in adult Thai patients with scrub typhus, caused by the obligate intracellular bacterium Orientia tsutsugamushi, and leptospirosis, caused by extracellular Leptospira interrogans. IFN-γ, interleukin (IL)-18, and IL-15 levels were elevated only in patients with scrub typhus, whereas IL-12p40 and tumor necrosis factor-α concentrations were elevated in both patient groups, although more so in scrub typhus. These data suggest a role for a cell-mediated immune response in host defense against O. tsutsugamushi. © 2004 Elsevier Inc. All rights reserved.|
