SURVIVAL AND GROWTH OF FIBROBLASTS IN VITRO

Abstract

In these studies normal guinea pigs were exposed to tuberculous cage mates in two different degrees of crowding, some in ordinary cages, where the food became contaminated with the excreta, laden with tubercle bacilli, of the inoculated animals, and some in special cages with wire-mesh floors, where these excreta were largely excluded as a source of contagion. The results are summarized in Table V.
