粘性放线菌(下简称粘放菌)是人类口腔内主要细菌成分之一,它与龋病和牙周病的发生有关。粘放菌与牙菌斑中其他细菌一样,定居牙面,形成菌斑,利用碳水化合物产生各种有机酸,使局部pH下降,造成牙面脱矿。本实验通过实验室培养,了解从当地人的口腔中分离出的粘放菌(AV855)生物特性,为进一步研究该菌致病机理提供资料。 Sticky actinomycetes (hereinafter referred to as sticky bacteria) is one of the main bacterial components in the human oral cavity, which is related to caries and periodontal disease. Like other bacteria in plaque, myxobacteria colonize the tooth surface and form plaque. Carbohydrates produce various organic acids, causing the local pH to drop, resulting in demineralization of the tooth surface. This experiment through laboratory culture to understand the local population from the oral mucoid bacteria (AV855) biological characteristics, to further study the pathogenesis of the bacteria to provide information.
