Streptococcus oral bacteria. Coloured transmission electron micrograph (TEM) of two Streptococcus sanguinis bacteria. They are undergoing nuclear division (mitosis), which results in two daughter cells. S. sanguinis, also called S. sanguis, is a normal inhabitant of the human mouth, particularly in dental plaque. It modifies the oral environment to make it less hospitable for other strains of Streptococcus that cause cavities. However, S. sanguinis can sometimes gain entrance to the bloodstream and accumulate in the heart valves. This causes bacterial endocarditis, which is an infection of the inner lining of the heart. If this occurs, antibiotics need to be taken in large doses to treat the infection. Magnification: x27,000 when printed 10 centimetres wide.
