Novel genetic sequencing methods revealed an overabundance of bacteria in a survey of public restrooms — from the doors and the floors to the faucet handles and toilet seats — with potential public health implications, according to findings recently published online in PLoS One.
Researchers at the University of Colorado at Boulder examined 12 public restrooms (six male and six female) in Colorado. Using a high-throughput genetic sequencing technique, they identified various bacteria on all of the surfaces they tested, according to a press release. The floor had the most diverse bacterial community, and human skin was the primary source of bacteria on all surfaces. Few differences were observed between the bacteria found in the male vs. female bathrooms.
The sequencing approach also allowed the researchers to determine the source of the bacteria they identified, including skin, soil and urine. This methodology could potentially help “analyze bathroom bacterial communities to identify proper (or improper) hygiene habitats, and that the exchange of bacteria on building surfaces may represent an important mode of pathogen transmission between individuals,” they said in the press release.
