Introduction: Despite advances in surgical technique and postoperative care, infectious complications associated with high mortality rates. Acinetobacter types around the globe has become an increasingly important nosocomial pathogens which cause infection. Liver transplant patients with Acinetobacter types can lead to peritonitis, bacteremia, pneumonia, urinary tract infection, which has a wide range of infection.

Materials and Methods: Between January 2001 and May 2013 in our clinic 355 patients have liver transplantation patients retrspektif age, etiology, Child score, duration of stay in the intensive care unit, surgical complications, presence and type of catheter, and which is taken from the cultures and antibiograms were antibiotic treatments. Multidrug-resistant Acinetobacter types were identified as resistant to all antibiotics except colistin

Results: Because of Acinetobacter types total 11 patients (3%) acinetobacter infections refractory to every kind of antibiyotics produced in 88 different cultures. Acinetobacter baumannii and Acinetobacter Iwoffiii ,Acinetobacter types were identified. Cause of bile duct infection (8 patients, 45 times), lung (1 patient, 4 times), intra-abdominal drain (4 patients, 15 times), blood culture (11 times in 4 patients), urinary tract (3 patients, 13 times). Age, length of stay in intensive care, Child-Pugh score, and etiology of patients infected with Acinetobacter important risk factors for morbidity and mortality were not. However, mortality among the patients infected with Acinetobacter types, respectively, when we compared with other patients mortality (27%, 11.5%), (p> 0.05) were found to be significantly higher

Conclusions: Acinetobacter types infection after liver transplantation in patients with significantly worse prognosis. Everything has been a major problem in center multidrug- resistant Acinetobacter types
