BREAKTHROUGH: Experts found the bacteria linked to multiple sclerosis (MS)!
Scientists have identified two strains of gut bacteria that may be directly involved in triggering multiple sclerosis (MS), offering a new path toward treatment or even prevention. In a groundbreaking study, researchers from Ludwig Maximilian University of Munich studied 81 pairs of identical twins where only one sibling had MS. This unique setup allowed researchers to isolate differences in gut microbiomes without the confounding factor of genetics. The bacteria Eisenbergiella tayi and Lachnoclostridium were found to be significantly more abundant in individuals with MS—and when introduced to mice, they contributed to MS-like symptoms, suggesting a causal role.
This is the most precise link yet between specific gut bacteria and MS, and it adds strong support to the theory that the gut-brain connection plays a central role in autoimmune diseases. While further research is needed to fully understand how these microbes influence immune responses in humans, the findings open the door to new therapies that could target or reshape the gut microbiome to prevent or reduce MS symptoms. The discovery marks a pivotal moment in MS research, moving us closer to microbiome-based treatments for this complex neurological disease.
