Antibiotic Susceptibility Testing for Clostridium Difficile Iraqi Isolation by using Disk Diffusion Method

Abstract

Multidrug resistance were investigated in 75 Clostridium difficile clinical isolates collected during the period of first of June 2013 till the end of april 2014. These isolates show ( 100% ) resistance to Colistin, Nalidixic acid, Cefotaxime, gentamycin, and high resistance to Clindamycin(95%), Ciprofloxacin(88%) , and moderate resistance to Erythromycin (65%), Ampicillin (53%), while show good sensitive to chloramphenicol ( 80%), and among these antibiotics, Vancomycin and metronidazol was the most effective antibiotic against Cdifficile isolates with high sensitivity (100%) ,(95%) respectively.
