Streptococcus mutans STRUCTURE AND PHYSIOLOGY
Streptococcus mutans is a Gram-positive, spherical, facultatively anaerobic bacterium found in the human oral cavity. This microorganism thrives in acidic environments and is known to form biofilms.
Streptococcus mutans TRANSMISSION AND DISEASE
S. mutans is commonly associated with oral disease and tooth decay. By metabolizing sucrose to lactic acid, S. mutans facilitates the demineralization of tooth enamel, resulting in dental caries. It has the potential to generate plaque and create dental biofilms. S. mutans can also lead to certain cardiovascular diseases and bacteremia.
Streptococcus mutans DISINFECTION
Fluoride and mechanical cleaning methods are most commonly used to help reduce the number of S. mutans bacteria. Antimicrobial rinses are also used to eliminate or reduce the presence of S. mutans plaques.
