褥疮感染分离菌株药物敏感试验分析

Analysis of drug sensitivity test of strain in bedsore infection

目的:鉴别1例褥疮患者的患部分离到的菌株并研究其药物敏感性。方法:从1例褥疮患者的患部分离到一株细菌,对其形态、染色等进行研究,对分离菌株进行菌种鉴定和药物敏感性试验。结果:Vitek 2系统结果显示分离菌株是肺炎克雷伯菌,该菌对阿米卡星、链霉素、妥布霉素、庆大霉素、氧氟沙星、环丙沙星、左氧氟沙星等药物敏感,K-B纸片琼脂扩散法结果显示分离菌株对红霉素、链霉素、氧氟沙星、阿米卡星敏感。结论:通过药敏试验结果选用左氧氟沙星对患者的感染进行治疗,收到良好效果,褥疮患者的感染及时得到控制,减轻了患者的痛苦。

Objective:To differentiate the strain separated from one patient with bedsore and study the drug sensitivity.Methods:A strain of bacteria was found from affected part of 1 patient with bedsore.We studied the morphology and staining,and we made strain identification and drug sensitivity test for the strain.Results:The Vitek 2 system results showed that the isolated strain was klebsiella pneumonia.The bacteria was sensitive to amikacin,streptomycin,tobramycin,gentamicin,ofloxacin,ciprofloxacin and levofloxacin.K-B disc agar diffusion method showed that the strain was sensitive to streptomycin,erythromycin,ofloxacin,amikacin. Conclusion:Through the results of drug sensitivity test,we used levofloxacin in the treatment of patients with infection,and the effect was good.The infection of patient with bedsore was controlled in time,which reduced the pain of patient.
