title: The association of blood groups, ABH secretion, haptoglobins and hemoglobins with filariasis.
abstract: Results on 605 patients and 597 controls carefully matched in relation to sex, age, marital status and profession are reported. A higher frequency of nonsecretors, as well as an excess of B and lack of A2 were observed among the filarial patients. Since these differences do not occur in other series, however, their significance is doubtful.
