title: Non-specific cell mediated immunity in patients infected with Schistosoma mansoni in Kenya.
abstract: Parameters of in vitro cell-mediated immunity (CMI) have been measured in the local Kenyan population infected with Schistosoma mansoni. Lymphocyte responses to the non-specific T cell mitogens Concanavalin A (Con A) and Phytohaemagglutinin (PHA) were reduced in about 60% of schistosomiasis patients. Lymphocytes from control uninfected, and S. mansoni-infected donors formed equal numbers of spontaneous rosettes with sheep red blood cells, indicating that there was no over-all reduction in the percentage numbers of T cells in the schistosomiasis patients.
