title: Contribution to the standardization of brucella abortus antigens and antisera for agglutination tests by photo-electric measurement.
abstract: Variations in the dose-response curve were graphically and arithmetically represented for the serum agglutination test in brucellosis, instances being given of the use in field conditions of a method of standardizing antigens and testing reference sera compared with standard preparations.
