Cultures of Staph. albus, Lact. odontolysogenes, B. coli, B. pyocyaneus and Candida albicans were grown on the blood-agar media containing homogenized tooth pulp of human and bovine origin at the rate of IO percent, and the pattern of growth, morphology, and staining of each organism was compared with that of control medium in an attempt to know whether or not the tooth pulp had a bacteriostatic ability, as it had been supposed by previous investigators. No difference, however, was detected between the media containing tooth pulp and the control media without it. And again pathogenicity of tubercle bacilli of human F and bovine types were examined by immersing them in the homogenized human and bovine tooth pulp for I to 5 days prior to the innoculum on the test animal, but no change in the pathogenicity seemed to have been induced by the procedure. So far as the present study is concerned, the author could not confirm the presence of the supposed inhibitory action of tooth pulp on the organisms tested.
