Resumen

Actinomycetoma, caused by the intracellular bacterium Nocardia brasiliensis, is characterized by an infiltration of several inflammatory cell populations. To explore aspects of the immune response in the pathogenesis of these bacteria we injected 106 CFU in footpads of BALB/c mice. After 1, 2, 3, 4, 7, 30 and 90 days immunohistochemistry was performed to compare presence and distribution of the inflammatory cytokines TNF-alpha, IL-1 beta, IL-6, IFN-gamma, IL-4, IL-10, and TGF-beta. Analysis of serial paraffin tissue sections showed strong participation and differences in distribution of cytokine-producing cells during the course of infection. Several TNF-alpha immunoreactive lymphocytes of the dermis were present during the course of the infection, but absent in the site of inflammation. During the first 4 days, IL-1 beta immunoreactivity was observed in dendritic epidermal cells and in cells surrounding the neutrophils around the grain. In later stages of infection, immunoreactive cells to this cytokine were mainly in the periphery of the microabscesses. Strong immunoreactivity was observed with IL-6 during the course of infection. Some cells in the epidermis and dermis, as well as muscle cells and several cells at the periphery of the microabscesses, showed strong IL-6 immunoreactivity. Cells immunoreactive to IL-4, IL-10, IFN-gamma and TGF-beta were present at the site of infection and, in later stages, in cells at the periphery of the microabscesses. In conclusion a mix of proinflammatory and antiinflammatory cytokines are produced at the same time by host cells. According to their distribution, inflammatory cytokines seems to have different functions during the course of infection with the intracellular bacterium N. brasiliensis.
