The study aim to detection antibiotic susceptibility and biofilm formation in clinical isolates of E. coli and Klebsiella spp. It was collected 264 different clinical specimens (193 urine,18 stool ,10 wound swabs ,4 vaginal swabs, 8 abscess ,5 bronchial liquid ,5 blood and 21 sputum . The results of study appeared 67 isolates (54 E. coli 54 and Klebsiella spp. 22) were isolated from 264 specimens .The result showed antibiotic susceptibility test a high resistance (100%) of enterobacterial isolates (E. coli and Klebsiella spp) were to ampicillin fo followed by amoxicillin/clavalunic acid ,it registered 29.59% and 90.91% respectively ,while imipenem was most active antibiotic agaist these isolates ,the sensitivity of isolates to this antibiotic was recorded 77.78% and 81.82% respectively. The study showed 57(75%) of both isolates were biofilm formation Klebsiella spp. Registered higher percentage (81.81 %) more than E .coli (72.22%),moderate biofilm was more frequently than other type of biofilm ,it was recorded 36.84% .we concluded the prevalence of biofilm producing multidrug resistant Enterobacterial isolates.
