Acinetobacter Baumannii

Acinetobacter baumannii is a water organism and preferentially colonizes aquatic environments. This organism is often cultured from hospitalized patients’ sputum or respiratory secretions, wounds or¬†urine. A baumannii is a multiresistant Gram-negative bacillus sensitive to relatively few antibiotics. Multidrug-resistant Acinetobacter is not a new or emerging phenomenon as A. baumannii has always been an organism inherently resistant to multiple antibiotics. Acinetobacter infections are uncommon but, when they occur, usually involve organ systems that have a high fluid content (e.g. the¬†respiratory tract, CSF, peritoneal fluid, urinary tract), manifesting as MDR nosocomial pneumonia, infections associated peritoneal dialysis (CAPD), or catheter-associated bacteruria .
