- Abstract
Objective: The aim of this study was to evaluate the effectiveness of peracetic acid and glutaraldehyde for the disinfection of alginate contaminated with Staphylococcus aureus as a function of immersion time (10 and 05 min). Materials and methods: The specimens were previously contaminated with S. aureus and then divided into six groups based on the disinfectant substance and immersion time. The samples were incubated in 20 ml of sterile BHI broth in an oven at 35 ± 2 °C and shakd at 100 rpm for 16 hours. Subsequently the samples of the broth from all the test tubes were plated to determine the presence or absence of viable cells. Results: The results showed that the control groups and that just washed in sterile water showed bacterial growth. Conclusion: The peracetic acid and glutaraldehyde was also effective for disinfection of alginate infected with S. aureus, both by immersion time of 10 and 5 minutes.
