Phylogenetic vs Physiological Modulation of the Microbiota

It should be emphasized that altering the microbial population dynamic is only one aspect of prebiotic action. While stimulating the proliferation of particular groups of bacteria might be important for some health effects (e.g., immunomodulation), this may be secondary to specifically altering the metabolic activity of the microbiota for other effects (e.g., anti-cancer). Marked differences between the phylogenetic and physiologic effects of prebiotics on particular groups of organisms have been observed (139). Because of its trophic and anti-neoplasic effects on the colonic epithelium, stimulating specific populations of butyrigenic bacteria in the colon may well be the next important target for prebiotics. In situ measurement of specific bacterial activities remains problematic, but advances in functional genomics may provide a new avenue to explore the interactions between prebiotics, the intestinal microbiota and the host in health and disease.
