Introduction: Enterococci are gram-positive microorganisms that are one of the most important causes of mortality in hospitalized patients and more than common causes of UTI. Enterococcus can persist or widespread in the hospital environment and to obtain antibiotic resistance indices. The importance of these bacteria has increased the ability to transmit resistance genes to other microorganisms and their role as a resistance scattering reservoir.
Methods: This study aimed to rate the prevalence and frequency of Enterococci strains among Gram-positive strains isolated from patients hospitalized in Shohada and Motahari hospitals in Gonbad.
Results: The results have shown that out of 120 samples Gram-positive strains collected from hospitals, 10 isolates are Enterococci. As well as, antibiogram test results by the disk diffusion method shown high resistance of much isolate to current antibiotics(Penicillin, Norfloxacin, Tetracycline, Cefoxitin, Nitrofurantoin, Trimethoprim, Rifampin, and Gentamicin).
Conclusion: the importance of Enterococci is their intrinsic resistance and the ability to quickly get resistance mechanisms to antibiotics against almost all available antibiotics. Today the resistance and their ability of these bacteria to be transmitted to other Genus have become a matter of concern.
