Biofilm formation by E. coli and S. aureus on cellphone cover: sensitivity to commercially available sanitizers

Presence of pathogens on the cellphones and their accessories poses a significant risk for public health. This study aimed to determine biofilm-forming capability S. aureus E. coli pieces made from different commercially available cell phone aadditionally test effectiveness most common sanitizers. Therefore, bacterial biofilm biomasses were quantitatively determined cellphone covers using crystal violet assay in presence absence revealed that could form biofilms surfaces all covers. Additionally, sanitizers contain sodium hypochlorite 5.25% those composed 38.9% ethanol 0.05% dodecyl dimethyl ammonium chloride showed highest log reduction number viable cells after 5 minutes exposure against formed by both compared other tested (chloroxylenol 4.8%, 2-propanol 64%, 70%). Moreover, 4.8% chloroxylenol 70% ethanol-based reductions significantly higher than 2-propanol-based ones. In conclusion, shown be suitable microbial formation produced . The antimicrobial activity these was variable, with ethanol/dodecyl sanitizer being effective.
