Effects of various antibiotics, sulfa drugs, and tuberculosis chemotherapeutics against the growth of Streptococcus faecalis were examined. All the antibiotics tested possessed a marked inhibitive action, but the action of the other two kinds gave varied results, mostly showing accelerating action. On the other hand, it was found that penicillin and homosulfanilamide, which possessed a marked growth inhibitive action, developed a certain amount of resistance by repeated culture of these bacteria.
