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.


The species identities were determined by appliying biochemical testing (ATB 32 Strep) together with complete 16S rRNA gene sequencing.
