Six glycolipid fractions can be extracted from lipid crude extracts of Canetti type strains of M. tuberculosis. Among these fractions are two phenolglycolipids. The major component is a triglycosyl phenolphthiocerol dimycocerosate (PGL-Tb 1) and the second is a monoglycosyl diacyl phenolphthiocerol identical to mycoside B of M. bovis. Similar glycolipid compounds can also be found in wild strains of M. tuberculosis recently isolated from tuberculous patients. One of these compounds has been identified as PGL-Tb 1.
