Streptococcus Mutans


Presentation

  • The entity represents a challenging diagnosis due to its variable and nonspecific clinical and radiological presentation and similarities with other conditions.[ncbi.nlm.nih.gov]
  • We therefore sought to characterize dendritic cell (DC) activation and antigen presentation following Streptococcus mutans exposure.[ncbi.nlm.nih.gov]
  • Despite its role in this important disease, our present knowledge of gene content variability across the species and its relationship to adaptation is minimal. Estimates of its demographic history are not available.[ncbi.nlm.nih.gov]
  • The results of the present study demonstrated that sRNA133474 activity was growth phase‑dependent, and two distinct expression patterns were identified in 10 clinical strains.[ncbi.nlm.nih.gov]
  • Origin Indigenous Geo Schema Political Region Geo Region New Zealand Occurrence Present Deprecated Name Ids '0fa40dd2-6939-43ef-b0a5-9467ef910be9' was deprecated on 14-Sep-2018 Scientific Name Authority Clarke Rank species Year 1924 Governing Code ICNB[nzor.org.nz]
Regurgitation
  • All of the heart valve tissue specimens were excised during a valve replacement procedure, following diagnosis of aortic regurgitation, mitral regurgitation, or tricuspid regurgitation, while the atheromatous plaque specimens were collected during treatment[doi.org]
Photosensitivity
  • The phototoxicity of photosensitizers against S. mutans was investigated using a colony-forming-unit assay.[ncbi.nlm.nih.gov]

Workup

  • His blood workup at presentation showed normal coagulation studies and his platelet count was low normal at 119 x 10 9 /L.[cureus.com]
Helicobacter Pylori
  • A combination effect of epigallocatechin gallate, a major compound of green tea catechins, with antibiotics on Helicobacter pylori growth in vitro. Curr. Microbiol. 47, 244–249 (2003). CrossRef Google Scholar 28.[doi.org]
Haemophilus Parainfluenzae
  • For example, the group of bacteria known as the sanguis streptococci has been found to produce nicotinamide adenine dinucleotide (NAD), which is then consumed by the species Haemophilus parainfluenzae (Liljemark and Bloomquist 1996).[web.archive.org]
Foam Cell
  • One of the crucial steps for the development of atheromatous plaque lesions is formation of foam cells, which are macrophages that accumulate from excess cholesterol, and P. gingivalis has been shown to enhance their formation ( 10 ).[doi.org]

Treatment

  • Many protocols for the prevention and treatment of oral infections have been described, yet no golden standard has been developed so far. The antiseptic chlorhexidine and antibiotics are often used in these treatment procedures.[ncbi.nlm.nih.gov]
  • Despite continuous efforts to control cariogenic dental biofilms, very few effective antimicrobial treatments exist.[ncbi.nlm.nih.gov]
  • Thus, this study aimed to determine the effect of tt-farnesol and myricetin topical treatments on cariogenic biofilms formed by Streptococcus mutans and Candida albicans.[ncbi.nlm.nih.gov]
  • The induced auto-aggregation of cells upon treatment could be due to the down regulation of vicK. Results of gene expression analysis demonstrated significant down-regulation of virulence genes upon betulin treatment.[ncbi.nlm.nih.gov]
  • Abstract Decalcification of enamel during fixed orthodontic appliance treatment remains a problem. White spot lesions are observed in nearly 50% of patients undergoing orthodontic treatment.[ncbi.nlm.nih.gov]

Prognosis

  • Guggenheim, Potential of Diagnostic Microbiology for Treatment and Prognosis of Dental Caries and Periodontal Diseases, Critical Reviews in Oral Biology & Medicine, 7, 3, (259), (1996).[doi.org]
  • These findings suggest a poor prognosis, or a higher tendency for recurrent bleeding in subjects with cnm -positive S. mutans strains. Figure 4: Recurrent ICH occurred in a patient with cnm -positive S. mutans.[nature.com]

Etiology

  • The usual etiologic agent is Staphylococcus aureus. We report a case of Streptococcus mutans endocarditis resulting in hematogenous osteomyelitis of the lumbar vertebrae.[ncbi.nlm.nih.gov]
  • Virulence traits, interactions in the biofilm, and influence of S. mutans in dental caries etiology are discussed.[ncbi.nlm.nih.gov]
  • Streptococcus mutans, a member of the human oral flora, is a widely recognized etiological agent of dental caries.[ncbi.nlm.nih.gov]
  • Mutans streptococci (MS), specifically Streptococcus mutans (SM) and Streptococcus sobrinus (SS), are bacterial species frequently targeted for investigation due to their role in the etiology of dental caries.[ncbi.nlm.nih.gov]
  • Abstract Streptococcus mutans is the primary etiologic agent of dental caries and occasionally infective endocarditis, with the ability to form biofilms and disperse cells into distal sites to exacerbate and spread infection.[ncbi.nlm.nih.gov]

Epidemiology

  • Precise differentiation of streptococci in bacterial endocarditis is of value both epidemiologically and in the management of the disease.[ncbi.nlm.nih.gov]
  • […] study provides new evidence supporting the use of the chairside SM Strip test or the qPCR assay for the detection and quantification of S. mutans colonisation in saliva as the analytical approach of choice for caries risk assessment in clinical and epidemiological[ncbi.nlm.nih.gov]
  • Author information 1 Department of Epidemiology for Community health and Medicine, Kyoto Prefectural University of Medicine, Kyoto, 6028566, Japan. 2 Department of Dental Medicine, Kyoto Prefectural University of Medicine, Kyoto, 6028566, Japan. 3 Department[ncbi.nlm.nih.gov]
  • Although S. mutans and S. sobrinus can be distinguished by appropriate laboratory tests, these are expensive and time-consuming so it is not always practicable to identify down to the species level in large-scale epidemiological studies.[web.archive.org]
  • Successful completion of these aims will establish a clear link between S. mutans persistent infection and chronic inflammation, and provide much-needed epidemiological insight of S. mutans association with CVD in the US.[grantome.com]

Pathophysiology

  • Its development is crucial in the pathophysiology of oral infections like dental caries, as well as in periodontal, pulp, and periapical diseases.[ncbi.nlm.nih.gov]

Prevention

  • Abstract Despite the widespread use of fluoride for the prevention of dental caries, few studies have demonstrated the effects of fluoride on the bacterial composition of dental biofilms.[ncbi.nlm.nih.gov]
  • MICHAEL DOI: [Download PDF] Abstract: Dental caries an ever growing public health problem is not much amenable to existing preventive measures.[ijpbs.net]
  • AIM: The aim of this study was two-fold: (1) To compare the antimicrobial efficacy of three commonly used chemotherapeutic agents in the prevention of ECC in comparison with a control and (2) To ascertain the role of chemotherapeutic agents in the prevention[ncbi.nlm.nih.gov]
  • CONCLUSION: Green tea mouth rinse can be a promising preventive therapy worldwide for the prevention of dental caries.[ncbi.nlm.nih.gov]
