| Popis: | Smartphones have become one of the most commonly used essential devices for daily communication. These devices are rarely disinfected, and contamination with various microbial agents may occur. Samples collected on smartphone touchscreens were analyzed to determine the counts of mesophilic aerobic bacteria, enterobacteria, molds and yeasts, total coliform bacteria and coliform bacteria at 45 °C. More than 70% of the analyzed apparatuses presented high contamination by aerophilic mesophilic bacteria and molds and yeasts, besides 25% by enterobacteria, being observed the presence of coliforms at 45 °C in 25% of the evaluated apparatus. The high contamination by aerobic mesophiles and molds and yeasts and the presence of coliform enterobacteria and bacteria at 45 °C suggest a health risk to users due to the possible presence of pathogenic organisms. |
