Description
Streptococcus mutans is a Gram-positive bacterium, commonly found in the human oral cavity and is a significant contributor to tooth decay. This bacterium, along with the closely related species Streptococcus sobrinus, can cohabit the mouth.
S. mutans is implicated in the pathogenesis of certain cardiovascular diseases, and is the most prevalent bacterial species detected in extirpated heart valve tissues, as well as in atheromatous plaques, with an incidence of 68.6% and 74.1%, respectively. Streptococcus mutans has been associated with bacteraemia and infective endocarditis.
