Scientists have discovered an interesting correlation between the bacteria living in the mouth, and the development of rheumatoid arthritis. It turned out that improper hygiene contributes to the progression of the disease and may be due to the severity of the symptoms, writes The Daily Mail.
Bacteria of the oral cavity participate in the development of enzyme peptidylarginine (PAD). The substance decomposes proteins of a particular group. The body identifies the remains of proteins as foreign particles, which occurs autoimmune reaction, according to scientists from the Dental school of the University of Louisville. Similar development mechanism has rheumatoid arthritis, which affects the joints, bones and cartilage. The disease is characterized by pain and restriction in the mobility of the limbs.
Scientists have found: in patients with rheumatoid arthritis gum disease are twice as often. Patients in some cases is determined by the bacterium Porphyromonas gingivalis. The enzyme converts proteins in acid, citrulline. It is determined by the body as a foreign agent with which to fight.
