Alterations in the T-lymphocyte subpopulation in patients with rhinoscleroma

Abstract

T-lymphocyte subpopulations were studied in a group of patients with rhinoscleroma due to Klebsiella rhinoscleromatis. The data demonstrated that these patients had a significantly greater number of T-suppressor/cytotoxic lymphocytes than did clinically healthy individuals. This finding correlated with a diminished response to the T-cell mitogen concanavalin A. The evidence indicated that the T-cell response of these patients was decreased and may reflect the host's response to the bacterial invader, thus explaining the chronicity of the disease.
