肛周脓肿脓液细菌培养及药敏分析

Analysis on the Bacterium Culture and Drug Sensitivity in Pus from Perianal Abscess Lesion

为探讨肛周脓肿脓液细菌分布情况及抗菌药物的敏感性和耐药性,选择我院2017年1月至2018年1月收治的60例肛周脓肿患者进行研究,抽取脓液进行细菌培养,并进行药敏试验。结果显示,在所检出的细菌种类中,革兰阴性菌株44株,革兰阳性菌株24株。检出的革兰阴性菌中,大肠埃希菌最多(23株,33.82%),肺炎克雷伯菌次之(8株,11.76%)。检出的革兰阳性菌中,粪肠球菌最多(11株,16.18%)。药敏试验结果显示,对于革兰阴性菌而言,哌拉西林舒巴坦抗敏感性最高,复方新诺明抗敏感性最低。对于革兰阳性菌而言,利奈唑烷抗敏感性最高,红霉素抗敏感性最低。结果表明,肛周脓肿多为混合细菌感染,以大肠埃希菌、粪肠球菌、肺炎克雷伯菌为主,复方新诺明和红霉素耐药率最低。临床工作中应结合药敏试验选用抗生素,成脓后应尽早手术治疗。

This study was to investigate the distribution and the sensitivity as well as the resistance to anti bacterial drugs of bacterium in pus from perianal abscess lesion, selected 60 cases of perianal abscess who admitted in author＇s hospital from Jan. 2017 to Jan. 2018 yr. as research objects, sampled their pus for bacterial cuhure,and taking drug sensitive test. As results, among the bacterial species detected G bacteria were in 44 strains,G＋ bacteria were in 24;in Gones E.coli occupied the most（23,33.82%）, Klebsiella pneumoniae the second （8,11.76%）;in G＋ ones Enterococcus faecalis occupied the most（11,16.18%）.As results for durg sensitivity,in G ones the anti-sensitivity of Piperacillin sulbactam was the highest,meanwhile Compound sinomin was the lowest;in G- ones, Linezoid was the highest, meanwhile Erythrocin was the lowest.Results show that perianal abscess could belong to multi-bacterial infection,predominated by E. coli ,Enterococcus faecalis and Klebsiella pneumoniae , which have the lowest drug resistance to compound sinomin and erythrocin,thus it should be according to drug sensitivity test results to choose antibiot- ics, once pustule formed as possible as early to take operative treatment.
