Cell mediated immune (CMI) responsiveness to soluble egg antigen (SEA) and its relation to the occurrence of schistosomal hepatosplenic disease in patients with schistosomiasis mansoni.
The delayed intradermal test and migration inhibition tests were used to assess the delayed hypersensitivity in patients with BHF and simple intestinal bilharziasis using SEA. All bilharzial patients gave a positive intradermal test. The specificity of the intradermal test using SEA is demonstrated clearly by the negative response in all control groups.
