STUDIES ON TUBERCLE BACILLUS-MONOCYTE RELATIONSHIP

Abstract
Studies of the conditions necessary for maintenance of constant cell populations in vitro in the Mackaness type of culture chamber have indicated the importance of preliminary trypsinization of cells and the beneficial effect of 40 per cent rabbit serum in Tyrode's solution. Under these optimal conditions, uninfected suspensions of monocytes exhibited little change in cell numbers over a period of 40 to 72 hours.
