title: The unfortunate role of precedent in bacteriology. II. Unrelated serological specificities of the polysaccharides from S. typhi and S. gallinarum sharing factors 9.12.
abstract: Tube and agar-gel precipitations of antigens isolated from S. typhi and S. gallinarum against homologous and heterologous rabbit antisera showed that the polysaccharides of these Salmonellae, sharing factors 9.12 do not cross-react. Thus, the serological analyses prove that sugars can not be related to factors in the Kauffmann-White scheme. The cross-reacting antigens from these Salmonellae of serogroup D are the free proteins and the proteinic moieties of their somatic antigens.
