Bacteria and Probiotics to Support Your Immune System
Saturday, May 14th, 2011A frustrated Dr. Alexander Khoruts had run out of ideas for treating a patient with a persistent gut infection of Clostridium difficile. Antibiotics weren’t working so Dr. Khoruts decided his patient required a transplant. He gave her some of her husband’s bacteria .
Prior to the procedure , they observed , her intestinal flora was almost non existant . “The usual bacteria just couldn’t be found in her,” said Dr. Khoruts. “She was inhabited by all kinds of misfits.” Two weeks after the transplant , the donated flora had taken charge . “That population was able to function and cured her disease faster than anyone anticipated” .
To say that the scientific community was surprised with the outcome is something of an understatement. It shouldn’t be. Scientists are frequently amazed by the complexity , power , and sheer number of bacteria that live in our systems . We have more than ten times more microbes than cells.
We all have populations made up of various species, but they generally fulfill the same necessary chemistry that we need to be healthy . One of those functions is breaking down complex plant molecules. We have a pitifully small number of enzymes encoded in the human genome, so we need additional bacteria . In addition to supporting the digestive function , the bacteria helps us in a variety of other ways. The microbes in our nose , for example, make antibiotics that fight off the dangerous pathogens we inhale .
In order to work in harmony with our microbiome own bacteria population , our immune system must tolerate myriad of harmless bacteria , while attacking pathogens . Researchers are seeing that the microbiome itself guides the immune system to the proper balance. One way the immune system fights pathogens is with inflammation. Too much inflammation can be damaging , so we also have immune cells that produce inflammation-reducing signals. With their ability to contain unrestrained free radicals, antioxidant populations also support an inflammation fighting function.
Scientists are finding new links between our inner flora and our health. They’re also finding that many conditions are accompanied by big changes in the makeup of our inner ecosystems. For example asthmatics have a different collection of microbes in their lungs than healthy people. Obese people also have a different set of species in their digestive tracts than people with normal weight.
Some surveys indicate that babies delivered by C- section are more likely to get skin infections since they possibly lack the protective covering of microbes from their mother’s birth canal. Caesarean sections have also been linked to a rise in allergies and asthma in children . So have the high use of antibiotics in the United States and other developed countries. Children who live on farms — can get a healthy dose of microbes from the earth — are less less likely to get autoimmune disorders than their peers who are raised in cities.
We consistently underestimate the importance of microbes and bacteria to our health and our medical profession has been too quick to take out their pads of paper and write up prescriptions for antibiotics and synthetic drugs. Digestive Enzyme supplements , probiotics and natural support for our immune systems might be a more thoughtful route to take in the future if we want to change this trend.
