开发龈下微生物膜生物膜的可重复性建模。

开发龈下微生物膜生物膜的可重复性建模。

材料与方法:在两名牙周健康者的龈沟处(探诊深度≤3mm)和牙周炎患者的四个深牙周袋处(探诊深度≥6mm)收集龈下菌斑样本。使用含有30%血清的蛋白胨培养基(Thompson等,Appl Environ Microbiol 2015; 81:8307-8314)和活性附着模型。在2周和4周时收取生物膜。通过单叠氮化丙啶处理阻断死细胞的DNA用于扩增。使用16S rRNA基因扩增子焦磷酸测序分析组成。使用Bray-Curtis相似性指数和相似性百分比分析,通过非度量多维尺度来评估生物膜样本之间的相似性。比较来自不同生物膜来源和不同生物膜时间的数据。

结果:非度量多维标度揭示了接种源,供体及其牙周状态的强聚类。在接种物来源(P = 0.0001)和生物膜时间(P = 0.0016)之间发现统计学显着差异。此外,牙周炎生物膜(P)在组成上不同于健康衍生生物膜(H):Porphyromonas(P = 19%; H = 0%),Filifactor(P = 10%; H = 0%),Anaeroglobus (P = 3%; H = 0%),Phocaeicola(P = 1.5%,H = 0%),Parvimonas(P = 19%,H = 14%),,Fusobacterium (P=2%; H=26%), Peptostreptococcus(P = 20%,H = 30%),Veillonella(7%,H = 8%)和其他57种属。相似距离(Bray-Curtis)(均数0.73,SD 0.15)和Shannon多样性指数(均数2,SD 0.2)显示重复实验之间没有差异(P = 0.121)。

结论:这种生物膜模型允许龈下微生物群落的可重复性建模。

Sci Rep:异位性皮炎患者皮肤表面细菌生物膜分析

异位性皮炎(AD)是一种慢性炎症性皮肤病,其特征是表皮屏障受损,先天免疫和适应性免疫失调,细菌易定植和感染。在本研究中,研究人员使用电子显微镜观察AD患者皮肤表面的细菌生物膜。结果显示,AD患者皮损中可发现金黄色葡萄球菌,产生了大量的生物膜。与浮游细胞相比,金黄色葡萄球菌生物膜对抗菌肽LL-37的易感性较差。共聚焦显微镜分析显示,LL-37结合到金黄色葡萄球菌的生物膜上。AD患者金黄色葡萄球菌生物

J Periodontal Res:上皮细胞对于健康和疾病口腔生物膜模型的反应

不同细菌刺激上皮细胞的反应不同。生物膜组成和活性可能影响上皮反应。通常用体外模型系统研究牙周炎相关细菌及其与宿主的相互作用;因此,理解影响生物膜 - 细胞相互作用的因素至关重要。本研究旨在开发体外单种和多种生物膜,并调查上皮对这些生物膜的反应。

J Dent Res:混合念珠菌种属生物膜应对抗真菌治疗时的动力学分析

念珠菌可以引起口腔感染,它是最常见的可分离出来的人真菌病原体,多与生物被膜相联系。虽然白色念珠菌是鹅口疮患者口腔的优势生物体,但由非白色念珠菌(包括:光滑念珠菌、都柏林念珠菌和热带念珠菌)引起的生物被膜口腔定殖和感染的发生率却在不断增高,而这些种属对抗真菌治疗通常具有更强的耐药性。目前,对单种属念珠菌生物膜的研究已经取得了一定的进展,但是对混合念珠菌种属的动力学分析以及它们在应对抗真菌治疗时的动力

J Clin Periodontol:用三氯/共聚物牙膏刷牙减少菌血症

本研究的目的是: 1)中度牙龈炎受试者的菌血症易患性的测试,2)比较三氯生/共聚物牙膏(实验组)与氟化物牙膏(对照组)对易患菌血症患者的影响。

Sci Rep:Ag-CFx可抑制细菌生物膜的形成,有效对抗感染

微生物的表面定殖导致生物膜的形成,即细胞外聚合物基质嵌入细菌中形成的聚集体。增加了细菌对表面的粘附,还可保护细菌群落,提供了抗菌抵抗的环境。抑制生物膜的生长是预防细菌感染的关键所在。通过离子束溅射沉积制备的无机纳米颗粒/Teflon样(CFx)复合材料表现出非常有效的抗微生物活性。在这项研究中,研究人员研发了具有可调金属负载的Ag-CFx薄膜,具有很好的平面形态和化学同质性。通过使用特别适用的多反

Clin Oral Investig:唾液和牙齿生物膜暴露于1500和5000 ppm氟化物后的差异分析

这项随机双盲交叉试验是为了检测在每天施加3次不同浓度氟化钠(0, 1500或5000 ppm)刺激3周后唾液和累积7天的生物膜流体和干物内的氟化物变化。
