The Human Microbiome - Quiz
The human microbiome is the collection of microorganisms that include bacteria, protozoa, fungi, viruses and other one-celled organisms in and on the body. Human-microbe interactions play a crucial role in individual health. The microbes are both external on the skin, mouth, genitals and internal in the lungs and digestive organs. The microbiomes have many essential functions in the body – from helping digestion, to supporting the development of the immune system and preventing infections. Impressively there are also interactions between gut microbes and the brain which means we may be able to support mental health through changing the gut microbiome.

Human Microbiome Quiz
Question 1 |
When do humans first come in contact with microbes?
A | In the womb |
B | During the birth process |
C | First day of school |
Question 1 Explanation:
Despite some ongoing scientific debate that the womb is not sterile, current evidence points mostly towards that humans live in a sterile environment in the womb and infants only start being colonized by microbes when going through the vaginal passage, or during skin contact with parents or the medical team.
Question 2 |
Can two people have the exact same microbiome (mix of microbes)?
A | Yes |
B | Yes, but only identical twins |
C | No |
Question 2 Explanation:
Everyone has a unique microbiota, like a personal fingerprint.
Question 3 |
How much of your entire microbiome is in your digestive track?
A | 50% |
B | 75% |
C | 99% |
Question 3 Explanation:
Nearly all our microbiome is located in the digestive track including the small and large intestine.
Question 4 |
When does your sweat start to smell?
A | When produced |
B | When metabolised by bacteria |
C | When doing intensive sports |
Question 4 Explanation:
Sweat has no smell until it gets metabolised by bacteria on the body which produces body odour.
Question 5 |
What technique to dry your hands is most effective in getting rid of bacteria?
A | Paper towel |
B | Fabric towel |
C | Hand dryer |
Question 5 Explanation:
A paper towel will reduce bacteria by 45-60%, while a hand dryer will increase the bacteria by 255% because it blows bacteria in a warm and moist environment in the air.
