6th Year MD-PhD Student, Rashid K. Rumah is the first author in the article: Toxin-Emitting Bacteria Being Evaluated as a Potential Multiple Sclerosis Trigger
A research team from Weill Cornell Medical College and The Rockefeller University has identified a bacterium it believes may trigger multiple sclerosis (MS), a chronic, debilitating disorder that damages myelin forming cells in the brain and spinal cord.
Their study, published in PLoS ONE, is the first to identify the bacterium, Clostridium (C.) perfringens type B, in humans.
The scientists say their study is small and must be expanded before a definitive connection between the pathogen and MS can be made, but they also say their findings are so intriguing that they have already begun to work on new treatments for the disease.
"This bacterium produces a toxin that we normally think humans never encounter. That we identified this bacterium in a human is important enough, but the fact that it is present in MS patients is truly significant because the toxin targets the exact tissues damaged during the acute MS disease process," say the study's first author, K. Rashid Rumah, an MD/PhD student at Weill Cornell Medical College, and the study's senior investigator, Dr. Timothy Vartanian, professor of neurology and neuroscience at Weill Cornell Medical College and director of the Judith Jaffe Multiple Sclerosis Center at New York-Presbyterian Hospital/Weill Cornell Medical Center.
"While it is clear that new MS disease activity requires an environmental trigger, the identity of this trigger has eluded the MS scientific community for decades," Dr. Vartanian says. "Work is underway to test our hypothesis that the environmental trigger for MS lays within the microbiome, the ecosystem of bacteria that populates the gastrointestinal tract and other body habitats of MS patients."
