ABSTRACT

Blood and saliva samples were collected from 93 Aotus nancymai and 20 A. vociferans monkeys. Saliva samples were tested for human ABH antigens by a conventional hemagglutination inhibition test which permitted us to assign 21 A. nancymai and 10 A. vociferans specimens to the B group, and 72 A. nancymai and 10 A. vociferans specimens to the O group.

Serum samples were used to detect natural antibodies, and the results showed some discrepancies between sera and secretion phenotypes as well as suggested the existence of anti-A1 antibodies in these species.
