J Periodontol: 阿米西汀对口腔密螺旋体及其他口腔螺旋体的抗菌活性

2018-12-30 MedSci MedSci原创

牙周病是一种多微生物感染,特征为牙龈炎,牙槽骨吸收和牙齿脱落。随着牙周病的发展,口服金黄色葡萄球菌(螺旋体)成为牙周袋中的主要细菌。口腔密螺旋体是厌氧菌,并且都编码丙酮酸 - 铁氧还蛋白氧化还原酶(PFOR),其催化丙酮酸氧化脱羧成乙酰-CoA。本研究旨在评估口腔密螺旋体对amixicile(AMIX)的敏感性,amixicile是一种新的PFOR抑制剂。

牙周病是一种多微生物感染,特征为牙龈炎,牙槽骨吸收和牙齿脱落。随着牙周病的发展,口服金黄色葡萄球菌(螺旋体)成为牙周袋中的主要细菌。口腔密螺旋体是厌氧菌,并且都编码丙酮酸 - 铁氧还蛋白氧化还原酶(PFOR),其催化丙酮酸氧化脱羧成乙酰-CoA。本研究旨在评估口腔密螺旋体对amixicile(AMIX)的敏感性,amixicile是一种新的PFOR抑制剂。

方法:研究测定了AMIX对几种口腔密螺旋体的最小抑制浓度(MIC)。确定了AMIX对与毒力有关的过程的影响,包括运动性,H2S产生和补体逃逸。

结果:所测试的口腔密螺旋体的生长受到AMIX的抑制,MIC浓度(MIC)范围为0.5-1.5μg/ mL。 AMIX显着降低了运动性,引起硫化氢产生的剂量依赖性降低和对人补体杀伤的敏感性增加(即血清敏感性)。

AMIX在体外有效抑制生长和毒力中心的其他过程。 AMIX可用作治疗牙周病的新选择性治疗工具。
