目的:分析口腔感染患者致病菌的分布及其耐药性。方法:选取2014年4月—2016年8月间诊治的口腔感染患者86例,采用药敏分析仪和全自动细菌鉴定仪分析和检测所得的致病菌。结果:86例口腔感染患者中,有60.16%为革兰阳性球菌感染,有31.25%为革兰阴性菌染,有8.59%为真菌感染;比较发现真菌与革兰阴性菌的构成比显著低于革兰阳性球菌(P<0.05);头孢哌酮和氨苄西林对铜绿假单胞菌、大肠埃希菌和肺炎克雷伯菌具有一定的耐药性。结论:革兰阳性球菌是口腔感染患者的主要致病菌,其耐药性的特点也是各不相同的,根据药敏结果合理选用抗菌药物治疗。
Objective: To analyze the distribution and drug resistance of pathogens in patients with oral infection. Methods: Totally 86 oral infections diagnosed and treated between April 2014 and August 2016 were selected. The pathogenic bacteria were analyzed and detected by drug sensitivity analyzer and automatic bacterial analyzer. Results: Among 86 cases of oral infections, 60.16% were gram-positive cocci, 31.25% were gram-negative and 8.59% were fungal infections. The comparisons between fungi and gram-negative bacteria were found to be significantly less than Gram-positive cocci (P <0.05); cefoperazone and ampicillin had certain resistance to Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumoniae. Conclusion: Gram-positive cocci are the main pathogenic bacteria in patients with oral infections, and the characteristics of drug resistance are also different. According to the results of drug susceptibility, rational use of antimicrobial drugs.
