Human brucellosis is a worldwide zoonotic infectious disease which is caused by intracellular bacteria belonging to the genus Brucella. Based on murine studies it has been shown that host resistance to Brucella depends on Th1 response, whereas Th2 response is involved in the severity of the disease. Since the immune response during human brucellosis has not been profoundly studied we have tried to evaluate cytokine production in patients suffering from brucellosis. Diluted whole blood samples were cultured in the presence of the mitogen, heat inactivated bacteria or medium alone. IL-12, IFN-gamma and IL-10 were measured by specific sandwich ELISA. In addition, the percentage of CD3(+) T cells producing either IL-13 or IFN-gamma was determined by flow cytometry. It was found that not only IFN-gamma production but also the number of CD3(+) IFN-gamma-producing cells decreased with prolongation of the disease but the percentage of CD3(+) IL-13(+) T cells were significantly increased. No correlation between duration of disease and IL-10 or IL-12 production was found. In conclusion, it is proposed that at the onset of brucellosis, Th1 response dominates white diminishing with prolongation of the disease. (C) 2005 The British Infection Society.
