Acinetobacter spp. - pathogenic role and resistance to antibiotics.

Acinetobacter species represent an important cause of nosocomial infections, producing urinary tract infections, pneumonia, endocarditis, wound infections, septicemia, meningitis. Acinetobacter were more frequent implicated in wounds infections (50.9%) and respiratory infections (20.4%). The infections 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 have been isolated during the study period were Acinetobacter calcoaceticus (11.14%), Acinetobacter haemolyticus (0.93%) and Acinetobacter lwoffii (0.93%). We obtained high percentages of resistent strains for all the tested antimicrobials, except carbapenems.
