Acinetobacter species which are widely distributed in nature and in the hospital environment are frequently associated with opportunistic infections in debilitated/immunosuppressed patients, those with serious underlying diseases as also those subjected to invasive procedures and treated with broad-spectrum antimicrobial agents, especially in intensive care units. This study aimed to evaluate antimicrobial sensitivity of A.baumannii against commonly used antibiotics. 130 isolates of A.baumannii from different clinical specimens were isolated and processed for antimicrobial sensitivity using Kirby Bauer disc diffusion method. Highest sensitivity was found for Imipenem and Meropenem (74.8%)followed by Netilmycin (65.9%)and Amikacin (43.1%) .
