【摘要】：目的分析口腔颌面部牙源性感染(OIOFR)的菌群分布特点,提高临床对口腔颌面部牙源性感染的诊治水平。方法对医院2012年1月-2013年4月收治的260例口腔颌面部牙源性感染患者的临床资料进行回顾性分析,并采用需氧和厌氧法对患者感染部位标本进行细菌分离培养,鉴定病原菌种类分析其分布特点,运用SPSS16.0统计软件对数据进行处理。结果 260例口腔颌面部牙源性感染患者共检出695株病原菌,其中厌氧菌402株占57.84%,需氧和兼性厌氧菌293株占42.16%;厌氧菌中以产黑色素厌氧菌、消化链球菌、普氏菌属、放线菌属、CO2噬纤维素菌、梭杆菌属和优杆菌属为主,需氧和兼性厌氧菌中以口腔链球菌、表型葡萄球菌、嗜血菌属和奈瑟菌属为主。结论口腔颌面部牙源性感染是以厌氧菌感染为主,且大多为需氧菌和厌氧菌的混合性感染,病原菌大部分来自于人体口腔正常的条件致病菌。
[Abstract]:Objective to analyze the microflora distribution of oral and maxillofacial odontogenic infection (OIOFR) in order to improve the clinical diagnosis and treatment of oral maxillofacial odontogenic infection. Methods the clinical data of 260 patients with oral and maxillofacial odontogenic infection from January 2012 to April 2013 were retrospectively analyzed. The distribution characteristics of pathogenic bacteria were analyzed and the data were processed by SPSS16.0 software. Results A total of 695 strains of pathogenic bacteria were detected in 260 patients with oral and maxillofacial odontogenic infection, of which 402 strains were anaerobic bacteria and 293 strains were aerobic and facultative anaerobic bacteria (42.16%). In anaerobes, melanin producing anaerobic bacteria, Streptococcus digestion, Pueraria, Actinomyces, CO2 Cellulose macrophages, Clostridium and Eubacillus are the main ones, and the aerobic and facultative anaerobic bacteria are Streptococcus oral and Staphylococcus phenotypic. Haemophilus and Neisseria are dominant. Conclusion odontogenic infection in oral and maxillofacial region is mainly caused by anaerobes, and most of them are mixed infections of aerobic and anaerobes.
