Streptococcus sobrinus - Wikipedia
Streptococcus sobrinus is a Gram-positive, catalase-negative, non-motile, and anaerobic member of the genus Streptococcus. [1] Pathology. Streptococcus sobrinus in conjunction with the closely related species Streptococcus mutans are pathogenic within humans and enhances the formation of caries within teeth.
Streptococcus sobrinus - an overview | ScienceDirect Topics
Streptococcus sobrinus is classified into serotypes d and g, with the prevalence of serotype d being higher and that of serotype g, quite low. The bacterium is reported to be isolated only from caries-active sites, while S. mutans has been isolated from both active and noncaries sites.
Streptococcus sobrinus - an overview | ScienceDirect Topics
Among the cariogenic bacteria, Streptococcus sobrinus is one of the key potent organisms in dental caries, usually present in a lower proportion than Streptococcus mutans until an individual shows a high level of caries index. But in all means pertaining to carcinogenicity, Streptococcus sobrinus is most cariogenic [141].

Streptococcus mutans and Streptococcus sobrinus are the most prevalent caries-associated microorganisms, 40 and Lactobacilli are a major contributor to caries progression. 41 Actinomyces, Bifidobacteriaceae, Granulicatella, Scardovia, and Veillonella have also been identified in early childhood caries. 42–45 Solobacterium moorei ...
Comparing the cariogenic species Streptococcus sobrinus and …
Two closely related species of mutans streptococci, namely Streptococcus mutans and Streptococcus sobrinus, are associated with dental caries in humans. Their acidogenic and aciduric capacity is directly associated with the cariogenic potential of ...

2010年9月16日 · From the genus Streptococcus, Streptococcus sobrinus is an anaerobic, spherical shaped, Gram positive bacteria. They grow in pairs or chains and are nonmotile, nonsporeforming. (1) Bacteria from this genus are usually pathogenic to humans and the S. sobrinus in particular lives in the tooth cavities of humans.
A Novel Competence Pathway in the Oral Pathogen Streptococcus sobrinus
2021年5月1日 · Streptococcus sobrinus is an etiologic cause of dental caries (tooth decay) in humans. Our knowledge of S. sobrinus is scant despite the organism's important role in oral health. It is widely believed that S. sobrinus lacks the natural competence pathways that are used by other streptococci to regulate growth, virulence, and quorum sensing.
Improved method for rapid and accurate isolation and …
Differentiation of S. mutans and S. sobrinus is an essential part of exploring the role of these organisms in disease progression and the impact of the presence of either/both on a subject’s caries experience. Of vital importance to the study of these organisms is an identification protocol that allows us to distinguish between the two ...
Characterization of the Streptococcus sobrinus acid-stress …
Streptococcus mutans and Streptococcus sobrinus are considered the primary organisms responsible for human dental caries. The ability to generate acids and to adapt to low pH conditions is directly associated with the cariogenic potential of these bacteria. To survive acidic conditions, both species have been shown to mount an acid-tolerance ...
