Abstract
Summary
Adult specimens of B. marinus maintained at 25°C were immunized with a mixture of S. typhosa H antigen and rabbit gamma globulin (RGG). Each animal produced precipitins for the RGG and agglutinins for typhoid H after a short period of immunization. When the antiserums were separated electrophoretically, the agglutinins were found in the slowest-moving of the 4 major serum components. On the basis of electrophoretic mobility, this fraction is analogous to the gamma globulin of mammals.
