Bacteria in Your Gut?
Rheumatoid arthritis, an autoimmune disease that attacks joint tissue and causes pain, affects 1.3 million Americans. Researchers have linked a species of intestinal bacteria known as Prevotella copri to the onset of rheumatoid arthritis. Of those tested, 75% of stool samples from patients newly diagnosed with rheumatoid arthritis carried Prevotella copri compared with 21.4% of samples from healthy individuals.
