Exposure to certain gastrointestinal bacteria may trigger multiple sclerosis (MS), the autoimmune disease that attacks the protective coating of nerve fibers and causes walking difficulties, muscle weakness, and numbness or tingling. Researchers at Robert Wood Johnson Medical School discovered that age, gut bacteria, and the genes associated with MS seem to trigger the disease, particularly in young adulthood. Continued research could lead to therapies that would eliminate harmful bacteria causing MS progression and enhance bacteria that would protect people against the disease.
