Effet de divers bois sur certains micro-organismesin vitro

Summary

Mycobacterium tuberculosis was brought into contact with stoved beech-tree wood in physiological saline solution. After a contact of 6, 12, and 24 h, respectively, between the beech-wood and the suspension of microorganisms in saline, this latter was sowed on Loewenstein culture medium. The suspensions which were in contact with the beech-wood for 6 h, gave cultures not different from the controls without wood. With the 12 h ones, the growth of mycobacterium tuberculosis was greatly delayed, whereas with the 24 h ones the cultures remained sterile.
