Antibacterial effects of silver nanoparticls nursing gowns ongeram- positive bacterial

Background and Aim : Background and Objective: Nosocomial infection is a major challenge inhealth care system. In fact, it is regarded as one of the risk factors in hospitalized patients. The aimof this study was to determine the antibacterial effect of silver nanoparticles (AgNPs) nursinggowns on germs-positive bacterial.Methods : Method: this descriptive and analytical study was done on ۲۰۰ nurses gowns weresurveyed in two hospitals of Sirjan city in Kerman Province central area of Iran. At first,antimicrobial activity of silver nano fabrics on Staphylococcus aureus bacteria was confirmed byexamining the optical density OD (۰.۳۲۵) medium. Sampling was gathered into the two mods,before using nano gowns and after using nano gowns by using wet sterile swabs. The samplecollected were cultured and the formations of colonies were examined and biochemical tests wereused to identify isolated bacterial.Results : Results: the most commonly isolated gram- positive bacterial from normal gowns wereStaphylococcus epidermidis (۴۳%) and the lowest pathogen was Streptococcus (۱%). In thesehospitals, after using nano silver gowns, the amount of microbial load on the clothes weredetermind zero.Conclusion : Conclusion: This study showed that gram- positive bacterials of nursing gowns aftercontact with silver nanoparticles were eliminated.
