In recent years, methicillin-resistant Staphylococcucs aureus (MRSA) have become a truly global challenge. Systemic review and meta-analysis was performed to summarize the prevalence of MRSA in different regions of Kingdom of Saudi Arabia (KSA). A search of the PubMed, Google and Google Scholar databases for studies published during the period of 1 January 2002 through 31 December 2012 was conducted. We included studies that looked at the number and prevalence of MRSA among total S. aureus. Meta-analyst and comprehensive meta-analysis were used for statistical analysis. Twenty six studies were included in the review, representing five regions of KSA. Pooled estimation of 22,793 S. aureus strains showed 35.6% (95% Confidence interval (CI), 0.28 –0.42; P < 0.01) of the strains were MRSA with significant heterogeneity. Prevalence of MRSA ranged from 5.97% to 94% in Dahran and Riyadh cities, respectively. MRSA proportion among KSA regions is slightly high and varied from one city to the other.Key words: Saudi – methicillin-resistant Staphylococcucs aureus -systemic review.
