What is the Origin of Limosilactobacillus Reuteri?

The organism was first isolated and named Bacillus reuteri in 1962, later reclassified to Lactobacillus reuteri, and recently updated to Limosilactobacillus reuteri based on comprehensive genomic analysis. The name honors the German microbiologist Ernst Reuter. This reclassification reflects the growing precision in microbial taxonomy.

What is the Mechanism of Limosilactobacillus Reuteri?

L. reuteri exerts its beneficial effects through several mechanisms, including competitive exclusion of pathogens and strengthening the intestinal barrier function. It also produces short-chain fatty acids (SCFAs) that nourish colonocytes and modulate systemic inflammation. Specific strains are known to modulate the gut-brain axis and immune response, and some research suggests they can influence the metabolism of sex hormones by altering the enzymatic activity of the estrobolome.

Limosilactobacillus Reuteri

Meaning

Limosilactobacillus reuteri is a species of Gram-positive, facultatively anaerobic bacterium that is a common and clinically significant resident of the mammalian gastrointestinal tract. Formerly classified under the genus Lactobacillus, this probiotic organism is recognized for its capacity to produce antimicrobial substances, such as reuterin, and for its beneficial immunomodulatory effects within the host. In the context of hormonal health, certain strains have been studied for their potential influence on the estrobolome and metabolic function. It is considered a beneficial commensal microorganism.
