Comparative Effect of Two Strains of C. parvum on Phagocytic Activity and Tumour Growth

Abstract

FOLLOWING the report of Halpern et al.1 that single or repeated injection of a killed suspension of a strain of Cornyebacterium parvum causes intense stimulation of lymphoreticular tissues, it was shown in our laboratory2 that intravenous injection of the same material either 2 days before or 8–12 days after subcutaneous inoculation of 105 or 104 viable mammary carcinoma cells in A strain mice significantly delayed the appearance of the tumour. Subsequently Halpern et al.3 found that the same strain of C. parvum markedly inhibited the growth of a transplanted mouse sarcoma.
