ABSTRACT

Blood and saliva samples were collected from 72 specimens of Chiropotes satanas utahicki captured on the west bank of the Tocantins river, Pará, Brazil. The saliva samples were tested for the presence of human ABH antigens by the standard method of hemagglutination inhibition. All individuals were classified as belonging to blood group A. Of 15 serum samples tested for anti-A and anti-B agglutinins, 13 showed only anti-B agglutinin and 2 showed neither antibody. Red blood cells were tested by the elution method for the presence of human A and B antigens. The results confirm the presence of the B-like antigen also detected in other New World monkeys, and suggest the occurrence of the A-like antigen.

Keywords: ABP blood groups; Chiropotes satanas.
