A scientific research answers a question that may seem trivial but it is not at all
Life is really strange! Sometimes a simple question is enough to mobilize an entire team of researchers, intent on demonstrating if it is true that farts carry germs in the air we breathe, especially in sterile environments.
The question that gave birth to everything was asked by a nurse, who had asked what would happen if, inside a sterile operating room, someone had to miss a fart. Would the environment be contaminated with germs?
Dr. Karl Kruszelnicki therefore wanted to investigate the issue scientifically. With the help of a microbiologist and a volunteer, he analyzed the germ content of farts.
The volunteer was asked to fart from a distance of 5 centimeters on Petri dishes, a tool for cell cultures, thus identifying the bacterial content. Two different tests were carried out: in one the volunteer was asked to dress normally, in another to fart without pants or underpants, so that the fart would arrive directly on the plate.
It emerged that without clothes the plates highlighted two different types of bacteria. In the case, instead, of farts passed through the clothes, the bacterial culture did not develop at all. Therefore, the underpants act as a filter for the bacteria that come out.
