Streptococcus sanguinis
(HMT-758)
Taxon Description:
Viridans type of streptococci has had taxonomic revisions [15]. Previously designated as strains of Streptococcus sanguis subsp. carlssonii. Will also see in the literature as Streptococcus sanguinis a proposed name change.
Disease Associations:
Generally associated with healthy oral microflora but has been associated with intact enamel in children with no caries [2]. However it has been suggested that it may play a role in caries production [3].Has also been associated with infective endocarditis and sinusitis. S. sanguis and other oral species have been linked to Behcet's disease a systemic disorder of recurrent acute inflammation including oral aphthous ulcers uveitis skin lesions and genital ulcers [4]

Prevalence and Source:
Commonly found in the human oral cavity and throat. Has been isolated from blood and heart valves of patients with bacterial endocarditis. May be found occasionally in human feces
