  • Title: A comparative study of anaerobic Coryneforms. Attempts to correlate their anti-tumour activity with their serological properties and ability to stimulate the lymphoreticular system.

    Abstract:
    Various strains of anaerobic coryneforms and the closely related Propionibacteria have been compared in vivo with respect to their anti-tumour activity. Their effectiveness has been correlated with their serological relationship and to some extent with their ability to stimulate the lymphoreticular system. Organisms belonging to Corynebacterium acnes groups I and II and C. avidum group IV were active anti-tumour agents, although of varying effectiveness. These strains are serologically closely related and all produce a soluble cross-reacting antigen. The single C. granulosum group III strain which we tested, an unclassified coryneform, and the classical Propionibacteria did not cross-react with the main group and had little or no anti-tumour activity. At the high dose (0.7 mg) we used, all strains, whether they inhibited tumour development or not, enhanced clearance of colloidal carbon and stimulated production of an inflammatory peritoneal exudate; at lower dosage the results were too variable to permit valid comparison. At the higher dose anti-tumour activity of a strain appeared to correlate best with ability to produce splenomegally and decrease red cell volume in the blood.
