title: Blood group active substances in Paragonimus westermani.
abstract: Lyophilized crude extracts of Paragonimus westermani were investigated for the presence of human blood group active substances, using an automated haemagglutination inhibition technique. This sensitive method allowed the detection of A, B, H, Lewis (a), Lewis (b) and P1 blood group specificities, in the fluke's extracts. No inhibition was observed with C, c, D, E, e, K, Kpa, Kpb, Fya, Fyb, Jka and Jkb blood group antibodies.
