Methicillin-resistantdetermined by the agar diffusion method, and methicillin resistance was confirmed by amplifying the mecA gene by polymerase chain reaction (Pcr). the prevalence of methicilin-resistant S. aureus (MrSA) was high in the burns (57.7%) and dermatology (39.4%) wards, and the MrSA strains isolated were extremely multi-resistant, but all of them were still susceptible to vancomycin. the rate of S. aureus nasal carriage was high in both cases and controls, in state, MrSA nasal carriage was more common among people infected with S. aureus.
