The normal indigenous intestinal microflora consists of
about 1015 bacteria that under physiological conditions
reside mainly in the lower gastrointestinal tract. Bacterial
overgrowth implies abnormal bacterial colonization of
the upper gut, resulting from failure of specific defense
mechanisms restricting colonization under physiological

Major burn is associated with decreased gut barrier function and increased bacterial translocation (BT). This study is to investigate whether commensal microflora induce host defense and decrease BT in burn mice. Methods: First, we treated Wild type (WT) mice with antibiotics in drinking water for 4 weeks to deplete gut commensal microflora. At week 3, drinking water was supplemented with lipopolysaccharide (LPS); a ligand for TLR4, to trigger TLRs in gut.
The human gastrointestinal tract microorganisms, termed the “microbiota,” have been
investigated since the beginning of microbiological studies, when Antonie van
Leeuwenhoek, the father of microbiology, investigated the microorganisms in his own
stools. The human microbiota comprises trillions of microbes distributed in various niches
throughout the intestinal tract and is one of the most complex microbial ecosystems on
Among them Lactobacillus and Bifidobacterium species were most
frequently cited and have been implicated in many human GIT disorders and have
become commercially promoted to improve the health of the host. The mode of action
of probiotics involves a mutual interaction with intestinal cells and other microflora
present in the gut. In these two chapters, the influence of probiotics on digestion,
absorption and barrier function, secretory functions and the postnatal maturation of
intestinal mucosa are described....
