Normal intestinal microflora

  • The normal microbiota of the intestine consists of all living microorganisms that inhabit the gastrointestinal (GI) tract:
    • Animals are born with a sterile GI tract, containing no bacteria; it is quickly populated with microorganisms after birth.
    • The composition of the normal flora changes as they grow, and once they reach adulthood, the composition remains fairly stable, with a small measure of variation in the proportions from day to day.
    • The small intestine in adult dogs can contain as many as 700 different strains of bacteria, while the canine large intestine may have as many as 5000 different strains.
  • The composition of the normal intestinal microbiota is unique to every individual animal, though a few very common bacterial groups are found in most individuals.
