AB  - BACKGROUND: Staphylococcus aureus is one of most prevalent pathogens in the world 
      associated with a high mortality rate and a rapid development of resistance to 
      antibiotics. Despite its pathogenicity, epidemiological monitoring in Mexico is 
      scarce. AIM: To analyze the local molecular epidemiology and determine the clonal 
      origin of methicillin-resistant (MR) strains isolated from patients admitted to 
      Hospital "Dr. Ignacio Morones Prieto". METHODS: A cross-sectional prospective 
      study was carried out from July to December 2016. The characterization of the 
      strains was carried out by Spa genotyping, frequency of specific virulence genes 
      by PCR and antibiogram. RESULTS: The prevalence of MRSA was 25.7%, highlighting 
      the presence of the Spa type t895 in 76% of the resistant strains and a similar 
      pattern of susceptibility to antibiotics. CONCLUSION: The results of this study 
      indicate that the regional prevalence of MRSA has not changed in the last 10 
      years and provide valuable information on the clonal origin and the virulence 
      factors of the strains of S. aureus isolated in the region.
