We decided to describe the clinical aspects associated to Acinetobacter baumanii nosocomial infections in the County Emergency Clinical Hospital in Sibiu and also their present susceptibility to antibiotherapy, evolution and prognosis. Nosocomial infections were generated by Acinetobacter in 95 cases out of 258, in tumoral diseases in 23 cases, politrauma or abdominal surgical interventions – 9 cases each, fractures – 13 cases with an unfavorable evolution in 7 cases. Th e sensitivity of the isolated stems is preserved in the cases of colistin – 98.15%, meropenem – 93.75% and imipenem – 86.02%.
