ON SPECIFIC INHIBITION OF BACTERIOPHAGE ACTION BY BACTERIAL EXTRACTS

Abstract

1. Experiments are presented demonstrating specific inhibition of phage by soluble products of bacteria. 2. The inhibition proceeds more rapidly when the phage and bacterial extracts are incubated at 37° than at ice box temperature. 3. The specificity of the reaction in the instances studied is probably connected with the presence of specific soluble carbohydrates. 4. A reaction is available for the study of the chemistry of bacillary antigens in terms of bacteriophage.
