Antibacterial Effect of Silver Nanoparticles (AgNPs) on Frequency of Aerobic Pathogens in the Nursing Gowns

Research on microbial contamination of individuals clothing has shown a variety of microorganisms. This contamination may cause infection and disease. The aim of this study was to Antibacterial effect of silver nanoparticles (AgNPs) on reduction of aerobic pathogens in the nursing Gowns of Sirjan hospitals in 2017.
The contamination of 200 nurses Gowns was surveyed in hospitals in Sirjan city. Sampling done in two modes, before using nano Gowns and after using nano Gowns by using wet sterile swabs. The colonies were examined and biochemical tests were used to identify isolated bacteria.
In Imam Reza Hospital & Dr. Gharzai Hospital, the most commonly isolated pathogens were Respectively Staphylococcus Epidermidis (57.83%) and Staphylococcus Epidermidis (51.35%) and the least pathogen respectively Pseudomonas (1.2%) and Escherichia Coli with Pseudomonas (1.35%). In these hospitals, after using nano silver Gowns, the amount of microbial load decreased significantly (eliminating roughly 100%).
In this study, the bacteria of nursing Gowns after contact with silver nanoparticles were eliminated, so the use of metal nanoparticles to cope with cross-infection can be effective.
