EXPERIMENTING WITH SILVER NANO DISINFECTION ON THE SURFACE OF TOYS FOR CHILDREN IN KINDERGARTEN SCHOOLS IN NINH KIEU DISTRICT IN 2022-2023
Main Article Content
Abstract
Background: Nano silver solution is a highly appreciated antibacterial agent, not harmful Objectives: Describe the current status of bacteria on the surface of toys and evaluate the antibacterial effectiveness of nano silver and chloramin B solution. Materials and methods: The research method of a randomized controlled trial on 80 people Toy samples at 10 preschools in Ninh Kieu district. Results: Percentage of types of bacteria existing on toys: Aerobic bacteria with more than 1 CFU/ml was 76.7%; fungi with more than 1 CFU/ml was 56.7%, Staphylococcus aureus was 13.3%; Candida was 26.7%. Antibacterial effectiveness of Chloramin B: Aerobic bacteria with more than 1 CFU/ml was 10%; fungi with more than 1 CFU/ml was 6.7%; There was no presence of Staphylococcus or Candida at 3.3%. Antibacterial effect of Nano silver 75ppm: aerobic bacteria with more than 1 CFU/ml was 6.7%; Staphylococcus was 3.3%; there was no presence of fungus and Candida. Conclusion: Initial results show that the effectiveness of nano silver was superior to choramin B. More research was needed to choose a safe and effective disinfectant solution in the school environment
