To investigate the effects of lactic acid bacteria administration on fecal microflora and putrefactive metabolites in human being, Lactobacillus acidophilus and Bifidobacterium longum powder (1.5 $ imes$ 10$^{9}$ cells, respectively) was administrated to six healthy volunteers (average 28 years old) twice a day for 2 weeks. During the administration of lactic acid bacteria, the numbers of bifidobacteria, lactobacilli, and enterococci in feces were increased significantly, whereas those of Staphylococcus and lecithinase-negative Clostridium were decreased considerably. In addition, a number of anaerobic Bacteroides were increased. However, the contents of fecal ammonia and putrefactive metabolites (indole, skatole, p-cresole) were not changed during the administration.
