Abstract
A strain of L. casei from a pharmaceutical preparation became established in the digestive tract of an axenic child. It was eliminated after inoculation of the child''s digestive tract with human bacterial flora, before the child was taken out of the isolator. In model gnotoxenic mice, the elimination of L. casei was apparently due to a bactericidal effect of the E. coli of human origin, within the digestive tract.
