Define Health Effects related to Probiotics?
Several lines of evidence support the conclusion that normal gut microflora are involved in resistance to disease, especially gastrointestinal infections. These are:
- Germ-free animals are more susceptible to infection than animals having complete gut flora,
- Orally administered antibiotics increase susceptibility of animals to infection (antibiotics are known to destroy gut microflora), and
- Administration of enemas of faecal suspensions from a healthy adult can control antibiotic-associated diarrhoea (AAD).
