Description
Streptococcus sanguinis is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. It is a non-motile, coccus-shaped bacterium that often forms chains or pairs. S. sanguinis is known for its role in the development of dental caries and endocarditis, a serious infection of the heart valves.
Pathogenesis
S. sanguinis is one of the first bacteria to colonize the tooth surface, playing an important role in the formation of dental plaque. It can also enter the bloodstream during dental procedures, leading to bacteremia and potentially causing endocarditis.
Treatment
Treatment for infections caused by S. sanguinis typically involves antibiotics. Penicillin is often effective, although resistance has been reported.
