Streptococcus sanguinis, formerly known as Streptococcus sanguis, is a Gram-positive facultative anaerobic[1] coccus species of bacteria and a member of the Viridans Streptococcus group. S. sanguinis is a normal inhabitant of the healthy human mouth where it is particularly found in dental plaque, where it modifies the environment to make it less hospitable for other strains of Streptococcus that cause cavities, such as Streptococcus mutans.
