title: [Experimental principles of immunotherapy using microbial substances in malignant tumors. 1. Effect of streptococci on ascite retothelsarcoma in the mouse in vitro].
abstract: The experimental results of Okamoto and his group with the preparation PB-B-45 from a strain of beta-hemolytic streptococci, group A, could be confirmed. The in vitro-method they used gives good results in the screening for strains of streptococci, which have antitumoral activity. With an own strain (no. IC) a complete inhibition of the growth of an ascites-retothelsarcoma of the mouse could be achieved by this technique.
