Abstract

INTRODUCTION

is a gram-negative,opportunistic pathogen responsible for resistant nosocomial infections especially in the intensive care units (ICUS).One reason for the failure in the treatment of is its ability of develop resistance against several antimicrobials. combination of different antimicrobials can be used to overcome such a resistance. This study was done to evaluate the in vitro synergistic activity of colistin in combination with six different antimicrobials, including ciprofloxacin, levofloxacin, imipenem, meropenem, ampicillin-sulbactam, and rifampin against species isolated from blood culture of patients admitted to ICUs of Nemazee hospital, Shiraz, Iran.

METHOD

After performing biochemical identification assays on 20 isolates of , minimum inhibitory concentrations were determined by E- test method and antibiotic interactions were assessed using broth microdilution checkerboard method.

RESULTS

Combinations of colistin with all six studied antimicrobials had some synergistic effect.

CONCLUSION

clinical studies are required to clarify the therapeutic potential of these antimicrobial combinations.

摘要

引言

[病原体名称]是一种革兰氏阴性机会致病菌,可导致耐药性医院感染,尤其是在重症监护病房(ICU)。其治疗失败的一个原因是它能够对多种抗菌药物产生耐药性。不同抗菌药物联合使用可克服这种耐药性。本研究旨在评估黏菌素与六种不同抗菌药物(环丙沙星、左氧氟沙星、亚胺培南、美罗培南、氨苄西林-舒巴坦和利福平)联合对从伊朗设拉子内马齐医院ICU患者血培养中分离出的[病原体名称]菌株的体外协同活性。

方法

对20株[病原体名称]进行生化鉴定试验后,采用E-test法测定最低抑菌浓度,并使用肉汤微量稀释棋盘法评估抗生素相互作用。

结果

黏菌素与所有六种研究的抗菌药物联合均有一定的协同作用。

结论

需要进行临床研究以阐明这些抗菌药物联合的治疗潜力。
