MULTIDRUG RESISTANT ACINETOBACTER BAUMANNII: A MAJOR CONCERN IN THE HOSPITAL SETTING

An attempt to estimate the significance of Acinetobacter baumanni for hospital pathology is done. The data obtained for five years period of time show that this microorganism is a problem predominantly for patients with respiratory tract infections, bloodstream infections and postsurgical wound infections in ICU. The strains resistance’ investigation to antimicrobial drugs shows high level resistance and multiresistance of A.baumannii strains developing significantly in the last years. Since 2004 it was also registered resistance of clinical A.baumannii strains to carbapenems. Our preliminary results demonstrate that 30.5% of the A.baumannii strains investigated carry genes, encoding VIM 1 enzymes, some of the strains comprise OXA 23 genes, but there were not detected genes, encoding IMP carbapemenases.
