A complicated scenario where "multiple disease threats coexist and multiple health influencing factors are intertwined" is demonstrated by the fact that dental caries, obesity myopia and scoliosis have emerged as global public health issues. The problem of diseases co-existing in living things can be resolved by using probiotics. , has gained attention recently due to its probiotic properties, useful traits, and potential medical applications.
Examining the anti-obesity and anti-caries effects of ATCC 14917 on dental caries and obese rat models caused by a high-fat and high-sugar diet is the aim of this study.
, we assessed the strain's probiotic properties, such as its antibacterial activity and ability to build biofilms, to determine its ability to inhibit . Prior to the experiment, the subsist test for ATCC 14917 was carried out by mimicking its capacity to lower blood sugar and blood lipid levels as well as its tolerance to gastrointestinal disorders. In order to assess the health promotion effect of . Three-week-old rats were fed a high-sugar, high-fat diet for 8 weeks. They were split into three groups: the control group (Control), the caries and obesity group (CA _OB) and the caries and obesity treated with ATCC14917 group (LP). ATCC 14917 was applied during the experiment, and the associated indices were then thoroughly assessed. These included the use of Mirco-CT to calculate the enamel volume, the staining of liver and fat cell sections, serological analysis, and 16S rRNA sequencing of feces.
It was proved that the could inhibit the proliferation of and remove dental plaque biofilm in time, which showed the remarkable effects of anti-caries . The demineralization rate of enamel decreased by 44.10% due to the inhibition of acid production by pathogenic bacteria. Moreover, In intestinal and stomach juice simulations, has a high survival rate. The characteristics of bacterial activity in a wide range of pH could degrade triglycerides and glucose smoothly. The LP group demonstrated it by reducing animal weight, serum biochemical indices, and HE-stained adipocytes as compared to the CA_OB group. 16S rRNA sequencing data showed that a high-fat and high-sugar diet induced the imbalance of intestinal flora, which showed an increase in microbial abundance, including , , , , . After the intervention of , the number of , , , , increased significantly.
Therefore, ATCC 14917 performed the potential of reducing tooth decay and controlling weight gain by a single strain. Support the management of dental caries and obesity, and establish a foundation for future functional food research and development.
龋齿、肥胖、近视和脊柱侧弯已成为全球公共卫生问题,这一事实表明了“多种疾病威胁并存且多种健康影响因素相互交织”的复杂情况。生物中共存疾病的问题可以通过使用益生菌来解决。由于其益生菌特性、有用特性和潜在的医学应用,最近受到了关注。
本研究的目的是检测ATCC 14917对高脂高糖饮食引起的龋齿和肥胖大鼠模型的抗肥胖和抗龋齿作用。
我们评估了该菌株的益生菌特性,如抗菌活性和形成生物膜的能力,以确定其抑制能力。在实验前,通过模拟其降低血糖和血脂水平的能力以及对胃肠道疾病的耐受性,对ATCC 14917进行了生存试验。为了评估其健康促进作用。将三周龄大鼠喂食高糖高脂饮食8周。它们被分为三组:对照组(Control)、龋齿和肥胖组(CA_OB)以及用ATCC14917治疗的龋齿和肥胖组(LP)。在实验期间应用ATCC 14917,然后对相关指标进行全面评估。这些包括使用微型计算机断层扫描(Micro-CT)计算牙釉质体积、肝脏和脂肪细胞切片染色、血清学分析以及粪便的16S rRNA测序。
证明该菌株可以抑制变形链球菌的增殖并及时清除牙菌斑生物膜,显示出显著的抗龋齿效果。由于病原菌产酸受到抑制,牙釉质的脱矿率降低了44.10%。此外,在胃肠液模拟中,该菌株具有较高的存活率。在广泛的pH范围内的细菌活性特征可以顺利降解甘油三酯和葡萄糖。与CA_OB组相比,LP组通过降低动物体重、血清生化指标和苏木精-伊红(HE)染色的脂肪细胞来证明这一点。16S rRNA测序数据表明,高脂高糖饮食导致肠道菌群失衡,微生物丰度增加,包括变形杆菌属、拟杆菌属、梭杆菌属、肠球菌属、葡萄球菌属。经过该菌株的干预后,双歧杆菌属、乳杆菌属、阿克曼菌属、粪杆菌属、瘤胃球菌属的数量显著增加。
因此,ATCC 14917展现出了单菌株减少龋齿和控制体重增加的潜力。为龋齿和肥胖的管理提供了支持,并为未来功能性食品的研发奠定了基础。
