Streptococcus mutans

Streptococcus mutans(Streptococcus mutans) IsGram positiveでFacultative anaerobic OfStreptococcusIt is a kind of.HumanOral cavityIt also exists insideCariesIt is one of the causative bacteria of (cavities).1924/Discovered by J Kilian Clarke.


Streptococcus mutans does not exist in the human oral cavity from the beginning, but by mouth transfer and sharing of tableware, infected peoplesalivaIs transmitted by getting into the mouth.In addition, to the same genusStreptococcus sobrinus(Streptococcus sobrinus) Etc., but all of them were considered to be Streptococcus mutans.but,DNAbyIdentification methodEtc. have been established, and it turns out that they are different fungi.

Highly pathogenic strain

Different from standard bacteriaSugar chainhaveglucoseStrains that do not have side chains are called highly pathogenic strains.White blood cellIt is hard to be phagocytosed by the blood, and bacteria are present in the blood.BacteremiaIt becomes a condition and causes pathogenicity to the whole body.Currently,cerebral hemorrhage,Ulcerative colitisSuspected of being involved in.

Infection with the highly pathogenic strain TW295Ulcerative colitisTo increase the risk of developingNikkei MedicalIs reporting[1][2].

Role in caries

The mutans group is classified into 7 bacterial species, but the ones present in the human oral cavity are Streptococcus mutans and Streptococcus sobrinus, both of which are involved in caries.Streptococcus mutans is retained in the cells酵素Depending on the group, the reaction of the caries process as shown below is activated.
