title: Blood groups of the mantled howler monkey (Alouatta palliata).
abstract: Fifty-two howler monkeys were tested for their human-type A-B-O blood groups. All were group B, as shown by the presence of B and H in their saliva, and anti-A in serum. The B-like agglutinogen of their red cells is common to all New World monkey species tested, and is of different origin and significance than their true A-B-O blood group. Differences among the B-like agglutinogens of the red cells of howler monkeys, marmosets, rabbits and humans group B were demonstrated, and limited tests have also been performed to study the biochemical basis of the anti-B reactions.
