Nosocomial Acinetobacter Infections

The number of nosocomial infections caused by Acinetobacter spp. has increased in recent years. In this study, we evaluated 80 patients (male 70% and, mean age of all patients 38.8 ± 12) with nosocomial acinetobacter infections. Fifty three (66.3%) of 80 strains identified by Sceptor were found to be as Acinetobacter baumannii and 27 (33.7%) strains to be as A. lwoffii. All Acinetobacter spp. were multidrug resistant. Quinolone and carbapenem resistance were 60.4% and 15.1% for A. baumannii, and 44.4% and 22.2% for A. lwoffii, respectively. Nosocomial Acinetobacter infections occurred after a mean (± SD) hospitalization of 14 ± 8.8 days. Most of infections (61.3%) were acquired in an intensive care and oncology ward. Of all patients, 76 (95%) had multiple risk factors. Nosocomial infections were as follows: pneumonia in 32 (40.8%), urinary tract infection in 16 (20%), wound infection in 14 (17.5%), bacteremia in 8 (10%), meningitis in 5 (6.3%), catheter infection in 3 (3.8%) and peritonitis in 2 (2.5%) of the patients. Acinetobacter infections caused or contributed to death of 13 (16.3%) patients.
