The diagnostic value of the rapid test with stained antigens vs. the tube agglutination test for pullorum disease. W. A. Higgins and C. H. Schroeder, Poultry Science, 12, 1933, No. 5, p. 323.

In this abstract of an article presented at the annual meeting of the Poultry Science Association in August 1933 it is reported that “a very close but not quite complete agreement was attained between the results from the tube agglutination test as compared with the rapid, whole-blood test when using stained antigens supplied by the U. S. Department of Agriculture, the Michigan State College, and two oommercial laboratories manufacturing the antigen under patent permit from the Bureau of Animal Industry. A third commercial antigen gave unsatisfactory results.
