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(More)
One effective treatment against sporotrichosis is the oral administration of potassium iodide (KI). It is not known how it works, and also it is not known if this substance has some effect on the microbicidal activity of polymorphonuclear neutrophils (PMN) and macrophages. In this work the phagocytic activity of gerbils treated with KI was studied. Gerbils(More)
Lymphocytes from 20 patients with NLL were cultured stimulated with PHA in presence of autologous and homologous plasma; the same procedure was carried out with lymphocytes from 20 healthy people, utilized as controls. A diminished capacity of transformation was noticed when lymphocytes, both from patients and controls, were cultured in plasma from NLL(More)
Sporotrichosis is characterized by a wide range of clinical manifestations from mild fixed cutaneous forms to systemic dissemination of the disease, despite an apparent regular pattern of virulence of the etiological agent, S. schenckii. These facts suggest that immunological mechanisms of the host could play an important role on the pathogenesis of the(More)
