Acinetobacter Spp. – Pathogenic Role and Resistance to Antibiotics

Abstract

Acinetobacter species represent an important cause of nosocomial infections, producing urinary tract infections, pneumonia, endocarditis, wound infections, septicemia, and meningitis. Acinetobacter was more frequently implicated in wound infections (50.9%) and respiratory infections (20.4%). The infection prevalence was bigger in the Orthopedy (19.4%), Intensive Care Unit (18.5%), and Plastic Surgery (14.8%) departments. Most of the isolated strains have belonged to the A. baumannii species (87%). Other Acinetobacter species that were isolated during the study period were Acinetobacter calcoaceticus (11.14%), Acinetobacter haemolyticus (0.93%) and Acinetobacter lwoffii (0.93%). We obtained high percentages of resistant strains for all the tested antimicrobials, except carbapenems.
