Resident
The term “resident” comes from Latin and means “to settle”. Resident bacteria are microorganisms that have settled in the microbiome over a long period of time. They have therefore “settled” in the intestine and remain there.
Transient bacteria
Transient (lat. transire = to pass by) bacterial strains, on the other hand, are organisms that do not settle in the microbiome. They are “just passing through” and are simply excreted by the body.
However, probiotics do not have to colonize the intestines to be effective!
Scientists have found that probiotics exert their effects primarily as transient bacteria . They travel through the digestive tract and interact with your immune cells, intestinal cells, nutrients and existing bacteria on their journey to provide direct and indirect benefits. Some improve gene expression in the signaling of the tight junctions that help protect against intestinal permeability - this means a tight intestinal barrier. The intestinal barrier determines which substances from the digestive tract can penetrate the intestinal wall into the body. A healthy intestinal barrier is therefore a protective wall that ensures that pathogenic substances and harmful bacteria are less able to penetrate the intestinal wall into the body - this in turn has a positive effect on your immune system.
Other transient bacteria promote the release of neurotransmitters that stimulate muscle contractions for increased motility, resulting in better and more regular bowel movements. When the intestines move regularly, food can be transported more effectively and conditions such as constipation can be avoided. There are also bacteria that produce byproducts such as short-chain fatty acids, which are beneficial for metabolic and intestinal health.
Continuous intake
However, since the transient bacteria are excreted at the end of their journey through our intestines, continuous intake is important. This is why probiotics only have the best effect on health when taken on a long-term basis.
