We used the recent recommendations (Magiorakos et al., 2012) to define MDR, XDR and PDR.

Thirty-one strains of Pseudomonas aeruginosa of human origin from The Institute of Cardiovascular Disease "Prof.  Dr. George I. M. Georgescu" in Iasi were tested by diffusion antibiogram. According to the results, strains were classified as MDR, XDR or PDR.

The quality control of the study was carried out with Pseudomonas aeruginosa strain ATCC 27853.

Results was 26 of the 31 strains that were tested were proven MDR, 5 strains were included in the XDR group, no PDR strains were found in this study.
