Abstract:
Aims:The aim of this study was to evaluate whether chewing gum affects mask contamination.
Methodology and results:Two groups of participants were requested to wear a mask for 15 min with (experimental group) or without (control group) chewing gum. Then, masks were collected and CFU calculation and 16S rDNA sequencing was performed. We found that temperature, humidity and bacterial CFU inside of the mask significantly increased when wearing a mask while chewing gum. Staphylococcus epidermidis was found in both groups. Staphylococcus aureus, Staphylococcus haemolyticus, Streptococcus oralis, Streptococcus parasanguinis and Bacillus wiedmannii were found in only the experimental group.
Conclusion, significance and impact of study:Chewing gum significantly increased the temperature, humidity and bacterial CFU inside the mask. Staphylococcus epidermidis, S. aureus, S. haemolyticus, S. oralis, S. parasanguinis and B. wiedmannii were detected inside the mask after chewing gum. - Full text:20.2023my0011.pdf
