The influence of glucosides on the growth of acid-fast bacilli, with a new method of isolating human tubercle bacilli directly from tuberculous material contaminated with other Micro-organisms. (Preliminary Note.)

Abstract This investigation was undertaken to test the action of acid-fast bacilli on the glucosides, and to see how far any fermentation reactions obtained would differ with the various strains of human and bovine tubercle bacilli tested, and also to obtain if possible a better medium on which to isolate and grow tubercle bacilli. In all, 43 glucosides were tested with acid-fast bacilli, including human and bovine tubercle bacilli. In all, 43 glucosides were tested with acid-fast bacilli including human and bovine tubercle bacilli, but there was no evidence of fermentation with any of the glucosides. One glucoside, ericolin, was found to kill off a large number of species of micro-organisms, especially bacilli of the colon group and various cocci, but had very little effect on the acid-fast group of bacilli.
