摘要

与口腔的全部菌群相比,存在于受感染根管内的细菌种类有限。根管中存在允许能够发酵氨基酸和肽的厌氧细菌生长的条件,而主要通过发酵碳水化合物获得能量的细菌则受到缺乏可用营养物质的限制。在感染过程中,微生物物种之间相互关系的发展和种群变化是这些相互作用的结果。某些物种之间存在着强烈的联系。这些联系很可能是基于营养需求和营养关系。多微生物根管菌群的致病性取决于细菌的协同作用。

Taxonomy, ecology, and pathogenicity of the root canal flora

The bacteria present in infected root canals include a restricted group of species compared with the total flora of the oral cavity. Conditions exist in the root canal that permit the growth of anaerobic bacteria capable of fermenting amino acids and peptides, whereas bacteria that mainly obtain energy by fermenting carbohydrates are restricted by lack of available nutrients. During the course of infection interrelationships develop between microbial species and population shifts are produced as a result of these interactions. Strong associations between certain species are present. These associations are most likely based on nutritional demands and nutritional relationships. The pathogenicity of the polymicrobial root canal flora is dependent on bacterial synergy.
