J Oral Microbiol:群体感应干扰剂可抑制链球菌菌膜的形成

2018-04-03 MedSci MedSci原创

既往研究已经提出将群体感应信号AI-2作为潜在靶标来防止变形链球菌(一种参与龋齿的病原体)形成生物膜。本研究旨在使用从海洋粘着杆菌20J获得的提取物干扰AI-2群体感应系统来抑制变形链球菌生物膜形成。使用生物传感器哈氏弧菌BB170和JMH597测试AI-2抑制活性。使用xCELLigence系统的阻抗实时测量、共焦激光显微镜和结晶紫定量方法,监测变形链球菌ATCC25175生物膜的形成。结果显示

既往研究已经提出将群体感应信号AI-2作为潜在靶标来防止变形链球菌(一种参与龋齿的病原体)形成生物膜。本研究旨在使用从海洋粘着杆菌20J获得的提取物干扰AI-2群体感应系统来抑制变形链球菌生物膜形成。

使用生物传感器哈氏弧菌BB170和JMH597测试AI-2抑制活性。使用xCELLigence系统的阻抗实时测量、共焦激光显微镜和结晶紫定量方法,监测变形链球菌ATCC25175生物膜的形成。

结果显示,与对照相比,加入粘着杆菌20J提取物后可将变异链球菌ATCC25175生物膜形成减少40-50%,而不会明显抑制其生长。在口腔链球菌DSM20627和牙齿链球菌7747生物膜中也观察到接近40%的降低。

研究结果表明,粘着杆菌20J可干扰AI-2并抑制变形链球菌中的生物膜形成。因此,群体感应过程的抑制可能是抑制牙菌斑形成的合适策略,但需要使用混合生物膜模型的其他实验来加以验证。
