Objective To analysis the results of the Bacterial culture and drug susceptibility in patients with perianal abscess,so as to guide clinical practice.Methods A total of 76 patients with perianal abscess who enrolled in hospital from August 2012 to February 2013 were selected for pus pathogens culture and drugs us susceptibility testing.Results In 76 patients,there were 70 cases with bacterial growth,accounted for 92.11％,There was no fungal growth.Totally 96 strains of pathogens were isolated from 76 patients,including 67 (69.79％) strains of anaerobic bacteria ; 75 (78.13％) strains of gram negative bacteria.Escherichia coli(54 strains) were the top pathogens isolated,accounting for 56.25％,followed by Pneumonia gram class Borrelia bacteria(16 strains),accounting for 16.67％ ; of 76 patients with perianal abscess,there were 47(67.14％) cases with mixed infections;the drug susceptibility testing showed that the susceptibility rate of gram negative bacteria to Imipenem was the highest,reaching 97.33％,and the susceptibility rate of gram positive bacteria to vancomycin was the highest,reaching 100％.There were 23 strains of ESBLS producing Escherichia coli isolates,accounting for 23.96％.Conclusion Perianal abscess are mostly caused by gram negative bacilli and anaerobic bacteria,the rational use of antimicrobial agents can effectively minimize the drug resistance,and effectively treatment the perianal abscess.%目的 分析肛周脓肿患者的细菌培养及药敏结果,以便指导临床用药.方法 我院2012年8月至2013年2月收治76例肛周脓肿患者,对其脓液进行细菌培养及药敏试验.结果 76例患者,培养有细菌生长的70例,占92.11％.本组均无真菌生长.共分离出病原菌96株.其中厌氧菌67株,占69.79％；革兰阴性菌75株,占78.13％.检出株数居首位的为大肠埃希氏菌,检出54株,占56.25％；其次为肺炎克雷伯氏菌,检出16株,占16.67％.76例肛周脓肿患者中,混合感染47例,占67.14％；革兰阴性菌对亚胺培南的敏感率最高,达97.33％；革兰阳性菌对万古霉素的敏感率最高,达100.0％.超广谱β-内酰胺酶(ESBLS)大肠埃希氏菌检出23株,占23.96％.结论 肛周脓肿是以革兰阴性菌和厌氧菌感染为主的混合性感染,合理使用抗菌药物可以有效降低病原菌的耐药性及有效治疗肛周脓肿.
