For the study of British scientists took about

electrical appliances for hands, as well as ordinary paper towels.
A group of researchers imitated a situation where the hands were

microorganisms are not characteristic of the flora of public toilets.
After using electrical devices, scientists collected samples.

Representatives of the Lactobacillus genus were found, namely those that
Also curious were the results of counting the number
- The air near the dryers contains 4.5 times more germs than
near ordinary dryers.
- In air masses near paper towels of microorganisms

In addition, airflow disperses bacterial
