Phosphatide Antigens of Mycobacteria

Abstract
Summary The nature of phosphatide antigens of 5 species of mycobacteria has been investigated by the kaolin-agglutination technique of Takahashi using serum from tuberculous patients as antibody source. The phosphatide antigens are present in virulent (H37 Rv, M. avium), avirulent (H37 Ra) and saprophyte (M. 607, M. phlei) strains of mycobacteria. The phosphatide antigens have been purified by silicic acid column and paper chromatography and identified as phosphatidyl inositomannosides.
