In this applied study، 40 persons of therapeutic Personnel including nurses، technicians، experts and patients from Zabol hospital and 40 students of Zabol University who were willing to participate in this research were selected.

Finally، by standardized tests، Staphylococcus aureus was detected. Then-PCR method، by using specific primers mecA، the Staphylococcus aureus was isolated. The results of this research showed that nasal carriers were 17/41 percent، throat carriers were 29/35 percent، nose/throat carriers were 76/11 and about 17/41 percent of all Staphylococcus aureus isolated، were resistant to methicillin. Due to the high rate of carriers of Staphylococcus aureus that resistant to methicillin، for Identifying these people and treat them in order to eradicate the infectious agent، can be one of the important ways to prevent hospital infections that in terms of the health and decreasing mortality، social، economic and health impacts is very important.
