Oral Bacteria and Bowel Diseases Mini Review

Masahiro Yoneda, Nao Suzuki, Hiromitsu Morita, Takao Hirofuji

Oral bacteria are considered to be associated with several systemic diseases. Recently, their association with inflammatory bowel disease (Crohn's disease and ulcerative colitis) and colorectal carcinoma has attracted much attention. In this mini-review, the association of oral bacteria with these diseases is briefly summarized. Fusobacterium nucleatum is known as a periodontopathic bacterium, and it is also associated with inflammatory bowel disease and colorectal carcinoma. Campylobacter concisus, which is found at the site of periodontitis, is associated with inflammatory bowel disease. Streptococcus mutans is a famous cariogenic bacterium, but a highlyvirulent strain of this bacterium is also associated with inflammatory bowel disease. In this way, both periodontopathic bacteria and cariogenic bacteria are associated with bowel diseases. Further epidemiological studies are necessary to reveal the cause and effect relationship between oral bacterial and bowel diseases.
