肛周脓肿脓液菌群分布及耐药性分析

Analysis on the Bacterial Flora Distribution and Drug-resistance of Pus from Perianal Abscess

为探讨肛周脓肿脓液菌群分布和对常用抗菌药物的耐药性，对53例肛周脓肿患者的脓液进行细菌培养及药敏试验。结果显示，本组24例（45．3％）未培养出细菌；29例（54．7％）培养出细菌，其中大肠埃希菌18例（62．1％），肺炎克雷伯菌5例（17．2％）。大肠埃希菌对亚胺培南、美罗培南、头孢吡肟的敏感性最高（100％）；对氨苄西林、复方新诺明耐药性最高（耐药率分别为88．9％和66．7％）。结果表明，肛周脓肿病菌以大肠埃希菌为主，对常用抗菌药物耐药率高。

Abstract By using the bacterial culture and antibacterial drug-sensibility test this study was to investigate the bacterial flora distribution and drug-resistance of pus from perianal abscess of 53 patients.As results,a- mong 53 cases 24 showed negative bacterial culture results（account for 45.3%） ,29 showed positive one（at-count for 54.7%） included E. coli in 18 cases（62.1%）, Klebsiella pneumoniae in 5 cases（17.2%）.The sensibility of E. Coli to imipenem,meropenem and cefepime was the most （100%）,but to ampicillin and compound sinomin, its drug-resistance was the most （the rate, 88.9%,66.7%, respectively）. Results show that among the bacteria from perianal abscess, E. Coli is predominant,has the high rate to common anti- bacterial drugs.
