Abstract
Summary1. The preparation of a sensitive and specific Vi agglutination reagent by sensitization of human type O erythrocytes with Vi antigen isolated from E. colt has been described. 2. Vi antibody content of rabbit and human sera was determined by this method and the conventional bacterial agglutination test. The hemagglutination test provided a more sensitive measure of Vi antibody by a factor of 3 to 6 fold. Greater variability in Vi titers was encountered in testing the sera of typhoid carriers; however, both methods were in good agreement in the detection of Vi antibody in these sera. The advantages inherent in the Vi hemagglutination procedure are discussed.
