本研究针对全球近50%人群罹患的龋齿问题，从健康人群口腔菌群中筛选出具有拮抗 Streptococcus mutans MTCC497 活性的细菌代谢产物。通过全细胞代谢物提取、GTFs（葡糖基转移酶）抑制实验及 C. elegans（秀丽隐杆线虫）毒性测试，发现 Enterobacter quasihormaechei 相关菌株 ...

本研究通过90天长期厌氧实验，揭示了Streptococcus mutans在人工唾液中加速316L不锈钢腐蚀的机制。实验表明，S. mutans形成厚度达88.1μm的致密生物膜，显著降低电荷转移电阻（LPR从1.5MΩ·cm2降至20.9kΩ·cm2），腐蚀电流密度增加295倍，最大腐蚀坑深度达5.3μm。XPS分析 ...

Got cavities? Blame Streptococcus mutans, a bacterium found in the mouth that produces acids strong enough to dissolve tooth enamel, allowing the microbe to bore into teeth and cause decay. Now, ...

Researchers have found in a new study that organic refined, organic virgin, and extra virgin coconut oils, along with ...

Researchers explore the pathogenic role of a surface protein expressed on Streptococcus mutans—a caries-causing pathogen—in IgA nephropathy The kidneys act as a filtering system in the human body that ...

An inter-disciplinary team of researchers led by Prof. Qian Peiyuan, Chair Professor at the Hong Kong University of Science and Technology (HKUST)'s Department of Ocean Science and Division of Life ...

In recent years, the adherence of microorganisms to surfaces or coatings has created major health risks to humans. Among these, microbial attachment and growth on surgical suture lines accounts for ...

New research provides compelling evidence that children acquire Streptococcus mutans, the bacterium most frequently associated with dental caries, from intra- and extra-familial sources besides their ...

There are many microbes that live in the human mouth, and while some are harmless, others like Streptococcus mutans are a major cause of tooth decay. It's thought that infants easily acquire these ...

A new study in the journal Microbiology Spectrum highlights the potential of using a natural compound from maple to combat the bacteria responsible for tooth decay: Streptococcus mutans. The compound, ...
