[Evaluation of immune response in experimental sporotrichosis using T and B lymphocyte count].

The effector cells of the immune response are involved in the clinical course of bacterial, viral and mycotic infections. Previous publications have reported that some mycotic infections, including sporotrichosis, can produce a negative modulation of the immune response unfavorable for the host. In this work T and B lymphocytes capable to form direct and indirect rosettes respectively with sheep erythrocytes in gerbils with experimental sporotrichosis, were measured. It was found a significant rise in the number to T and B lymphocytes which means normal immunological reactivity. These results are not in accordance with the idea that sporotrichosis can depress the immune response of the host.
