Human germ cloud: New study finds millions of identifiable bacteria surround every person

The video discusses how individuals emit unique microbial clouds, which can be used to identify them. Researchers found that microbes differ in unoccupied and occupied spaces due to body movements. By placing three people in a room, they identified each person by their microbial signature. While the types of germs are similar, their ratios vary per person, with gender differences evident, such as the presence of Lactobacillus in women.

What forms our personal germ cloud?

• The clothes we wear

• The food we eat

• The microbes we shed

• The air we breathe

How do researchers differentiate between microbes in occupied and unoccupied spaces?

• By the temperature of the room

• By the color of the microbes

• By the size of the microbes

• By the particles emitted during movement

What was the duration of the experiment where individuals were identified by their microbial signatures?

• Five hours

• Four hours

• Three hours

• Two hours

What is a key factor that makes microbial signatures unique to each person?

• The type of food they eat

• The amount of exercise they do

• The ratio of different germs

• The color of their skin

Which microbe is more commonly found in women?

• Bacillus

• Lactobacillus

• Escherichia

• Staphylococcus
