Summary
Researchers identified 19 different types of germs in public toilets on the University of Colorado. They realized most of them are from human skin. The detail unveiled by the new study. Researchers used to gather several bacteria from their own circumstance. Most of samples had been microscopic and unclear existences, but the new study was carried on by using a specific gene, and because of the gene, such tiny bacteria showed themselves very clearly. Then, researchers investigated how such bacteria spread all over the place. They acknowledged most of the bacteria were existed at the entrance door knobs of toilets, toilet seats, flush handles, faucets, soap dispensers, and the floor around the sink. The reason of dispersal bacteria seems to be human feces. As some considerable situation, the hand is unclean, or when people flushed toilet water including feces or urine splashes and a is aerosolized. Some of bacteria prefer to women's toilet because they like female genital tracts. The researchers say when people consider about cleanness very seriously, people must wash their hand very much after using a bathroom.
My opinion
I previously wrote about flies. This time, I knew the scientists who are interested in bacteria in toilet. I am really interested in scientists mind. And, I realized the most doubtful clue which contaminate various bacteria is humans' hand. I do not care washing hand well, but I try to do that right now.

Koji, I am surprised to know that you did not care about washing hands carefully before!!! Haha~ but at least I know that your hands will always be clean! :)
ReplyDeleteI always wonder about ways of greeting in different cultures. Take Chinese people for example, I heard that for some personal hygiene issues, they always shake left hands (assuming that most people are right-handed). Did you know about this? :) Isn't it interesting?
haha. Surprisingly I HAVEN'T cared washing hand so far. But I try yo do because if I do not wash hand after toilet, I will be the origin to contaminate your class with many bacteria. Do you remember? I use the restroom many times per day(I said the very first beginning in your class).
