Curcumin suppresses Streptococcus mutans adherence to human tooth surfaces and extracellular matrix proteins
1Department of Biological Sciences, College of Natural Sciences, Wonkwang University, Iksan, Chonbuk, 570-749, Korea.
Summary
Curcumin effectively inhibits Streptococcus mutans adherence to tooth surfaces and extracellular matrices like collagen and fibronectin. This anti-adhesive property suggests curcumin
Area of Science:
- Microbiology
- Biochemistry
- Dental Research
Background:
- Streptococcus mutans is a primary pathogen responsible for dental caries and infective endocarditis.
- Bacterial adherence to host surfaces is a critical initial step in biofilm formation and disease progression.
Purpose of the Study:
- To investigate the inhibitory effect of curcumin on Streptococcus mutans adherence to extracellular matrices and human tooth surfaces.
- To determine if curcumin's anti-adhesive action is mediated by collagen and fibronectin.
Main Methods:
- Assessed the adherence of S. mutans to collagen- and fibronectin-coated glass surfaces in the presence of varying curcumin concentrations.
- Evaluated curcumin's effect on S. mutans adherence to human tooth surfaces in vitro.
- Determined the minimum inhibitory concentration (MIC) of curcumin for S. mutans growth.
Main Results:
- Curcumin demonstrated an anti-adhesive effect against S. mutans at concentrations below its minimum inhibitory concentration (MIC) of 128 μg/mL.
- Curcumin significantly reduced bacterial adherence to both collagen- and fibronectin-coated surfaces.
- The inhibitory effect was also observed on human tooth surfaces, indicating relevance to oral conditions.
Conclusions:
- Curcumin exhibits significant anti-adhesive properties against Streptococcus mutans.
- The anti-adhesive mechanism of curcumin appears to involve interference with bacterial binding to collagen and fibronectin.
- These findings support the potential of curcumin as a food-based antimicrobial agent for preventing S. mutans-related diseases.

01:27The Oral Microbiota
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
01:25Clinical Significance of Antibiotic Resistance
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
01:29Biofilms
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...
01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
01:24Drugs for Peptic Ulcer Disease: Sucralfate as Mucosal Protective Agents
In the intricate landscape of the gastric lumen, excessive acid secretion disrupts the natural defense mechanisms, weakening the mucus-bicarbonate barrier. This vulnerability allows pepsin to infiltrate epithelial cells, digesting mucosal proteins and triggering erosion, leading to ulcer formation.
In this scenario, mucosal protective agents like sucralfate play an essential role. Sucralfate, a complex of sulfated sucrose and aluminum hydroxide, demonstrates its usefulness in acidic conditions,...
