Table 1 Eight newly sequenced mutans streptococci strains

From: A genome-wide study of two-component signal transduction systems in eight newly sequenced mutans streptococci strains

Species Strain Short description
S. mutans 5 DC8 Serotype c, isolated from root caries by David Beighton (London, UK), alterations in 16S sequence in comparison to type strain.
S. mutans AC4446 Serotype c, isolated from a proven case of infective endocarditis in Dillingen (Germany).
S. mutans KK21 Serotype c, isolated from enamel caries of an adult by Susanne Kneist (Jena, Germany), potent producer of bacteriocin.
S. mutans KK23 Serotype c, isolated from enamel caries of a child by Susanne Kneist (Jena, Germany), potent producer of bacteriocin.
S. mutans ATCC25175 Type strain, serotype c, isolated from carious dentine, quality control strain.
S. mutans NCTC11060 Serotype f, isolated in Denmark from a patient's blood (bacteremia), reference strain.
S. ratti DSM20564 Type strain (= ATCC19645), serotype b, isolated from caries lesion in rat, nearest neighbor to species S. mutans with a 94-95% similarity on 16S level.
S. sobrinus DSM20742 Type strain (= ATCC33478), serotype non-d & non-g, isolated from human dental plaque, 93% similarity with S. mutans on 16S level; considered as a relevant cariogenic species in human.
  1. The species identities were determined by appliying biochemical testing (ATB 32 Strep) together with complete 16S rRNA gene sequencing.
