Antituberculous Factors of Milk

MILK and milk-whey have been found to contain one or more anti-tuberculous agents 1 . The administration of milk, milk-whey or the dialysate of the latter which passed through a ‘Cellophane’ membrane, inhibited the development of experimental tuberculosis in the mouse. The question arises whether an inhibitory influence on the mycobacterium is responsible for this effect. If so, the material obtained from milk should be effective in vitro . In vitro experiments with milk, milk-whey and its dialysate were therefore performed.
