80例口腔凳面部感染的厌氧菌分析

目的 确定８０例口腔颌面部感染的细菌类型，研究厌氧菌在其中的分布及厌氧菌代谢产物在其鉴定中的辅助作用。方法 对脓液标本进行分离培养，同时应用ＧＬＣ技术分析厌氧菌代谢产物辅助确定厌氧菌种、属。结果 ８０例口腔颌面部感染的脓液标本全部分离出细菌。厌氧菌检出率９５．００％，分布于８个属、２９个种，检出率高的厌氧菌依次为消化链球菌、消化球菌、类杆菌、菜杆菌、韦荣氏菌、真杆菌等。厌氧菌与需氧菌混合感染率为８

Anaerobes analysis in 80 cases with ora maxillofacial infections]

OBJECTIVE:To define the infection types of 80 cases of ora-maxillofacial infection and investigate its anaerobes' distribution and the role of the anaerobes' metabolic products in their identification.METHODS:We isolated and cultured anaerobes from the purulent specimen and applied the gasliquid chromatograph (GLC) technique to analyze the anaerobes' metabolic products to define their genera and species in the meantime.RESULTS:Bacteria were isolated from all of the purulent specimen.Isolation rate of bacteria was 100.00% and isolation rate of anaerobes,which distributed in 8 genera,29 species,was 95.00%. The higher detectable rate of them were respectively peptostreptococcus,petococcus,bacteroides,fusobacterium,verillonella,eubacterium. The rate of mixed infection was 80.00%. The proportion ratio of aerobes and anaerobes was 1:1.08.CONCLUSION:Oral-maxillofacial infection mostly belongs to endogenous mixed infection in which anaerobes are preponderant bacteria. GLC technique is a effective,sensitive,selective and specific method for defining anaerobes' genera and species through analyzing their metabolic products. It is a promising and recommendable rapid anaerobes' identification method comparatively at present.
