MUTANS-SANGUIS AGAR

Streptococcus mutans is gram-positive, facultatively anaerobic bacteria commonly found in the human oral cavity and is a significant contributor to tooth decay. They metabolize sucrose to lactic acid. Sucrose is the only sugar that S. mutans can utilize. S. mutans is found in dental plaque, in blood, on heart valves in subacute endocarditis, and infrequently in saliva and throat specimens. Streptococcus sanguis is also a part of oral flora and preferentially colonize the tooth surface. Mutans Sanguis Agar is recommended for differentiation of S. mutans and S. sanguis.
