Infant immune system interactions with commensal (friendly) bacteria not only teach these cells friend from foe but also encourage secretions of secretory IgA (sIgA), the antibody found in the protective mucus barrier of the gut lining; decreased sIgA is associated with decreased immune defenses.
Their results make for important reading as a fibre - deprived gut was associated with the rise of some rather potent bacteria that seemed to enjoy dining out on the «colonic mucus barrier, which serves as a primary defense against enteric pathogens.»
«But our work shows that from a mucus barrier perspective, that is not a good enough distinction,» says Lai.
That mucus barrier protects the intestinal walls from both the disease - causing and beneficial bacteria.
The researchers discovered that during periods of dietary fiber deficiency (in other words: a diet that's not too dissimilar to a typical nutrient - deficient Western diet), the gut microbiota resorted to breaking down the colonic mucus barrier to obtain nutrients.
Our bodies accomplish this through something called the colonic mucus barrier.
The microbes in our intestines do not colonize the tight inner layer of the mucus barrier, but as enzymes that we and our bacteria produce break down the sugar and protein backbones of the barrier, a loose outer layer is formed that supports a diverse population of microbes.
Now, scientists are beginning to understand that dietary fiber also supports the integrity of the intestinal lining by preventing the degradation of the colonic mucus barrier.
Not surprisingly, when the mucus barrier was degraded, susceptibility to enteric pathogens (pathogens that threaten the intestines, specifically) increased.
These types of bacteria, if not kept in check, can wreak havoc on the colonic mucus barrier.
If present in sufficient numbers, they may degrade the mucus barrier faster than the body can replenish it.
Bear with me as I give a quick lesson on the colonic mucus barrier and how it's maintained.
When the gut microbiota is starved of their favorite food (dietary fiber), they'll begin to look for other things to eat, including, it seems, the complex polysaccharide matrix of the colonic mucus barrier.
The colonic mucus barrier is produced by specialized cells in our gut epithelium lining that secrete mucin.
Based on the study described here, we are wise to consume no less than the daily recommended amount of fiber because it's possible that certain microbes may take matters into their own hands by invading our personal space and degrading the mucus barrier that is designed to keep us safe.
Their results make for important reading as a fibre - deprived gut was associated with the rise of some rather potent bacteria that seemed to enjoy dining out on the «colonic mucus barrier, which serves as a primary defense against enteric pathogens.»

SIBO may develop if the normal host defence mechanisms, such as gastric acid secretion, intestinal peristalsis, the ileocaecal valve, intestinal immunoglobulin secretion, and mucus barrier are impaired.
