Streptococcus salivarius
Streptococcus salivarius (undesignated strain) is a species native to the human oral cavity and upper respiratory tract, where it is one of the first bacteria to colonize at birth. S. salivarius has been studied for oral and throat health applications, particularly with named strains such as K12 and M18; without a strain designation, strain-specific evidence cannot be attributed to this entry. The species is a common commensal of the healthy human mouth and throat.
