Researchers add to evidence that common bacterial cause of gum disease may drive rheumatoid arthritis -- ScienceDaily

In a report on the work, published in the Dec. 14 edition of the journal Science Translational Medicine, the investigators say the common denominator they identified in periodontal disease (gum disease) and in many people with rheumatoid arthritis is Aggregatibacter actinomycetemcomitans. An infection with A. actinomycetemcomitans appears to induce the production of citrullinated proteins, which are suspected of activating the immune system and driving the cascade of events leading to rheumatoid arthritis."
