Introduction
Acinetobacter baumannii is one of the most important opportunistic pathogens causing serious complications. In Kuwait in recent years the prevalence of resistance to antibiotics has raised serious concern especially in the intensive care units. Resistance to carbapenems is mainly caused by the OXA type enzymes; however resistance to cephalosporins are caused by chromosomal AmpC or by extended spectrum beta-lactamases, such as PER.
