【 摘 要 】

Abstract Objective One of the most important causes of nosocomial infections is Staphylococcus aureus. The aim of this study was to determine the frequency of these genes and the rate of expression of these genes during nasal colonization among the personnel of Kashani and Hajar hospitals. Results In this Analytical-descriptive study, 240 nasal swab specimens were collected from personnel of different departments of Kashani and Hajar hospitals in Shahr-e-kord. Nasal specimens were cultured and 110 Staphylococcus strains were isolated. Based on the results, 110 carriers of Staphylococcus aureus were identified. The frequency of clfA, clfB, fnbA and fnbB genes were 36.3%, 86.3%, 7.2% and 43.6% respectively. It was also observed that the fnbA gene showed no expression, but of 95 clfB-positive samples, 73 isolates (76.8%) were expressed clfB gene. This study showed that the abundance of these genes varies in nasal colonization. It was also observed that clfB gene with a high frequency and high expression rate has an important role in nose colonization. These results not only provide insight into the factors involved in S. aureus colonization but also provide potential therapeutic targets.
