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。
OBJECTIVE To analyze the distribution characteristics of bacterial flora causing odontogenic infections at oromaxillo-facial region （OIOFR） so as to improve the diagnosis and treatment level of OIOFR .METHODS The clinical data of 260 cases of OIOFR patients who were treated in the hospital from Jan 2012 to April 2013 were retrospectively analyzed ,and the specimens obtained from the infection sites of patients were put into isolation culture through aerobic and anaerobic process ;the distribution characteristics were analyzed after identification of pathogen types ,and SPSS 16 .0 software was adopted for processing the data .RESULTS Totally 695 strains of pathogens were detected from 260 OIOFR patients ,with 402 strains （57 .84% ） of anaerobes and 293 strains （42 .16% ） of aerobes and facultative anaerobes ;anaerobes were dominated with Black-pigmented anaerobes , Peptostreptococcus ,Prevotella ,Actinomyces ,CO2 Cellulophaga ,Fusobacterium and Eubacterium;aerobes and facultative anaerobes were dominated with Streptococcus oralis , Phenotypic staphylococcus , Haemophilus and Neisseria .CONCLUSIONS OIOFR is mainly caused anaerobic infection , and mostly by mixed aerobes and anaerobes;most of the pathogens are the common conditioned pathogens from the oral cavity of people .
