口腔颌面部牙源性感染病原菌分布特点分析

Distribution characteristics of pathogens for oral and maxillofacial odontogenic infections

目的分析口腔颌面部牙源性感染病原菌分布特点,探讨优势病原菌的检出率,为临床诊断提供依据。方法回顾性分析2010年9月-2012年12月医院接受诊治的口腔颌面部牙源性感染患者167例临床资料,对其病原菌分布特点进行探讨,采用SPSS13.0进行分析。结果 167例口腔颌面部牙源性患者共检出病原菌436株,其中厌氧菌253株占58.03%,需氧及兼性厌氧菌183株占41.97%;检出的前3种病原菌依次为口腔链球菌、产黑色素厌氧菌、消化链球菌,分别占27.52%、13.52%、11.01%。结论口腔颌面部牙源性感染中链球菌属为其最优势菌,其次为产黑色素厌氧菌、消化链球菌、普氏菌属等。

OBJECTIVE To analyze the distribution characteristics of pathogens for oral and maxillofacial odontogenic infections,and discuss the detection rate of the predominant pathogens,in order to provide reference for clinical diagnosis.METHODS A retrospective analysis was conducted for the clinical data of 167 patients treated for oral and maxillofacial odontogenic infections in our hospital during Sep.2010-Dec.2012,the distribution characteristics of the pathogens were discussed,and analyzed using SPSS13.0.RESULTS In the 167 cases of patients with oral and maxillofacial odontogenic infections,436 strains of pathogenic bacteria were detected,of which 253 were anaerobic bacteria,accounting for 58.03%,and there were 183 strains of aerobic and facultative anaerobes,with a proportion of 41.97%.The top 3pathogenic bacteria detected were oral Streptococci（27.52%）,melanin producing anaerobic bacteria（13.52%）,and Peptostreptococcus（11.01%）.CONCLUSION In the oral and maxillofacial odontogenic infections,Streptococcus was the most dominant bacterial species,followed by melanin producing anaerobes,Peptostreptococcus,and Platts spp.
