Mode of action of probiotics
In eubiosis the major proportion of the intestinal microflora consists of desirable microorganisms. Certain microorganisms which are intentionally added to the feed (probiotics) counteract possible disruptions of the equilibrium and help to reestablish
eubiosis. Thus the colonisation of the intestine by undesirable microorganisms can be suppressed. As yet, not all actions of probiotics have been satisfactorily explained by
science. Their overall positive effects, based on developing metabolic activity, comprise both direct and especially indirect
effects (Figure 3). In general, the
following modes of action of probiotics
are assumed:
