应用严格的厌氧技术，稳定的环境条件，对西宁地区30例中老年漫性根尖周炎患者根管内厌氧菌的细菌学研究。结果表明，分离培养的主要厌氧菌属，以感染的频率依次为消化链球菌、拟杆菌、放线菌、梭杆菌、丙酸杆菌、韦荣氏球菌等八属。感染的类型是以厌氧菌为主的混合感染。厌氧菌的感染率为97％，需氧菌感染率为3％。由于中老年人机体的免疫功能降低，使厌氧菌长期存在造成慢性感染。
Application of strict anaerobic technology, stable environmental conditions, 30 cases of elderly patients with diffuse apical periodontitis in Xining anaerobic bacteria bacteriological studies. The results showed that the main anaerobes isolated and cultured in order of frequency of infection were Peptostreptococcus, Bacteroides, actinomycetes, Fusobacterium, Propionibacterium, Veillonella, and other eight genera. The type of infection is an anaerobic-based mixed infection. Anaerobic infection rate of 97%, aerobic bacteria infection rate of 3%. Due to the lower immune function in the elderly, the anaerobic bacteria cause chronic infection.
