Background and objective: Methicillin resistant Staphylococcus aureus(MRSA) is a main cause of
nosocomial infections worldwide. Multidrug resistance property of strains causes difficulties in treatment of
their infection. The aim of this study was to determine the frequency of MRSA and their resistance pattern to
commonly used antibiotics in Health-educational centers of Gorgan.
Material and Methods: In this descriptive study, 121 clinical isolates of Staphylorcoccus aureuscollected
from different infections from September 2008 to August 2009. After confirmatory identification tests, the
antibiotic susceptibility testing was performed by using disk diffusion method as per Clinical and
Laboratory Standards Institute(CLSI) guideline. Data analyzed by Chi-square test and SPSS soft ware. P
value of <0.05 was determined as significant.
Results: Of 121 tested S.aureus, 104(85.9%)strains were MRSA. The highest resistance was demonstrated
as:100% to Penicillin, 97.6% to CO- Amoxyclav ,71.4% to Cephotaxime and64.3% to Erythromycin. Our
finding showed more MRSA isolates in urine (90.4%) and wound (89.2%) specimens.
Conclusion: Prevalence of MRSA strains in our region was 85.9% .This is higher than other studies
performed in major cities such as Tehtan,Mashhad and Shiraz . The treatment of infections caused by
MRSA is difficult due to simultaneous multidrug resistance among the strains
