"For decades scientists have combed the gut looking for bacteria in the microbiome that push the immune system toward multiple sclerosis (MS). New evidence from a rare twin study now points a clear finger at two species of bacteria that hide in the small intestine.

The study, which compared 81 pairs of genetically identical siblings, singled out Eisenbergiella tayi and Lachnoclostridium as the most likely triggers of the nerve‑damaging disorder.

Dr. Anna Peters of Ludwig Maximilian University of Munich steered the international team that linked these bacteria to disease in both people and mice.

Tracing clues in identical twins
Identical twins share nearly every gene, so differences in health are often related to outside factors. By focusing on twins where only one sibling had MS, the researchers stripped away much genetic noise."
