HBSAg antigenaemia in bilharzial patients.

: The frequency of HBSAg in bilharzial patients (7%) was significantly higher than that in non bilharzial ones (2-5%). The presence of insulted liver by bilharzial, non bilharzial (C.P.H. and C.A.H.) or both (C.P.H. with bilharzia and C.A.H. with bilharzia) lesions have no role in changing the incidence of HBSAg in sera of bilharzial patients.
