: pseudomonas aeruginosa is one of the most opportunistic pathogens and as one of the main factors of hospital infection. the aim of this study was to determine the antibiotic resistance of pseudomonas aeruginosa strains isolated from samples of isolates in clinical trials.


In this descriptive cross-sectional study, in 2017, sampling for 2 months, treatment centers, city of sari. by performing biochemical diagnostic tests and the use of differential environments, on 40 samples (wound and urinary tract), 30 samples infected with pseudomonas aeruginosa. in order to assess the pattern of antibiotic resistance, disk diffusion method was used.


As a result of this research, the greatest resistance to ampicillin (34.83%) and tetracycline (66.76%) and the lowest resistance to amikacin and tobramycin (%10) view.


The present study suggests that the potential problems of bacterial resistance in the country and the province. so with the supervision of the treatment of antimicrobial activity and reviews the test sensitivity in vitro with adherence to antibiotic treatments, policies can be used to control the spread of drug-resistant germs make it easy.
