Acinetobacter infections are one of the causes of hospital-acquired pneumonia, blood infection, urinary tract infection, skin or wound infection and nosocomial meningitis. It complicates the dialysis and can cause catheter-associated bacteruria. The occurrence of Acinetobacter isolates in respiratory discharges in intubated patients may symbolize colonization. Caution must be exercised in defining whether the isolate is because of colonization or is truly causing infection.
Acinetobacter is colonizing mostly in irrigating solutions and intravenous solutions such as patient’s respiratory secretions, wounds and urine. Acinetobacter usually colonize rather than causing infection in respiratory secretions and urines of the recovering patients but are capable of infecting organ transplants and febrile neutropenia.
