Evaluation prevalence of methicillin resistant staphylococcus aureus relative of nasal colonization in Primary school children in khoramabad in 1396

Introduction: Staphylococcus aureus is one of the earliest known organisms in humans, and the species of this bacterium are the most important pathogens in humans. It can cause local infections or life-threatening attacks in all age groups, which can be transmitted either directly or indirectly between individuals. The aim of this study was to evaluate the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in elementary school students in Khorramabad.Materials and methods: In this cross-sectional study, 320 school children in Khorramabad were selected through the stratified cluster randomized sampling. The samples were taken from the nose and sent to the lab and cultured on the Mannitol Salt Agar culture medium. The grown colonies were selected for catalase and coagulase tests. The confirmed colonies were isolated for methicillin sensitivity test. For this purpose, the Meller-Hinton Agar culture medium and 1 μg oxacillin disk were used.Results: A total of 86 (26.9%) of the samples had positive staphylococcal culture, of whom 37 (23.1%) were male and 49 (30.6%) were female. Of all the samples, only one case (0.3%) had positive MRSA culture. The prevalence of golden Staphylococcus aureus was higher in the girls. Also, there was no significant relationship between the prevalence of MRSA with gender, education, parental education, parental occupation, place of residence and number of family members.Conclusion: The results of this study indicated that colonization with golden methicillin-resistant Staphylococcus aureus is present among healthy children who are not at risk. Fortunately, the prevalence of MRSA in this area is not high in comparison with other areas, but more attention is needed to prevent the transmission of such resistant species. It is recommended that antibiotic resistance should be monitored and controlled continuously, and necessary training for the individuals and health care workers involved in patients administration and care should be undertaken on a regular basis.
