英國醫學雜誌假期特輯上的研究：放屁會不會帶出細菌? Do farts carry germs? Well, it depends on whether you are wearing pants.
實驗方法：堪培拉(Canberra)某研究機構的微生物學家做的一項研究---對著培養皿放屁，還分了穿著褲子和脫了褲子的對照組。。。結果顯示脫了褲子放屁會釋放細菌而穿著褲子不會，但進一步分析顯示這些細菌並不會造成危害---酸奶裏也有這些細菌。
好吧，這不是火箭科學。不過話說回來，不知是不是？
He asked a colleague to break wind directly onto two Petri dishes from a distance of 5 centimetres, first fully clothed, then with his trousers down. .....
Our deduction is that the enteric zone in the second Petri dish was caused by the flatus itself, and the splatter ring around that was caused by the sheer velocity of the fart, which blew skin bacteria from the cheeks and blasted it onto the dish. It seems, therefore, that flatus can cause infection if the emitter is naked, but not if he or she is clothed. But the results of the experiment should not be considered alarming, because neither type of bacterium is harmful. In fact, they’re similar to the ‘friendly’ bacteria found in yoghurt.
Our final conclusion? Don’t fart naked near food. All right, it’s not rocket science. But then again, maybe it is?
