Study: dryers unsafe hands. Use paper towels

Microbiology Group at the University of Connecticut in the April issue of Applied and Environmental Microbiology published a study Deposition of Bacteria and Bacterial Spores by Bathroom Hot-Air Hand Dryers air in the hand dryers.

It turned out, the suction device germs and dangerous pathogens emitted into the air after draining the water in the toilet bowl, and then bombarding them just washed hands. Using the filter in the dryer is able to reduce the amount of harmful microbes, but totally solve the problem in this way is still not succeed.

The course of study

Part of the petri dish just left in the toilets for two minutes, the other part was placed under a hot air dryer for 30 seconds, and then calculated the resulting bacterial colonies. It was found that the largest number of colonies, namely from 18 to 60 appeared in the plates left under air from the dryers. On plates that were just standing in the toilet, they found less than one colony.

The study also noted that the use of antibacterial filters in dryers reduces the total number of microbes is about four times, but still did not get rid of them completely.

Hand dryers absorb harmful bacteria and they are attacking you.

results

Most often, in Petri dishes occurred hay bacillus spores Bacillus subtilis - not dangerous to human bacterial species. However, also present and other microorganisms, causing dangerous diseases. These include Staphylococcus aureus, Clostridium, which are the causes of skin diseases, pneumonia, meningitis and sepsis.

What to do if you do not want to get infected

Safer and more hygienic to use paper towelsThan hand dryers. They effectively remove residual water, and in the course of friction bacteria are transferred to the paper. By the way, in the university, where the study was conducted, after the results have been delivered dispensers for paper towels.
