The Benefit of Being a Dirty Pig
Summary:
In the article it mentioned that adults are always keeping their kids clean like making them wash their hands. However scientists think keeping too clean might be harmful to the children. They did an experiment on piglets they raised some indoor and some outdoor. To their surprise the ones raised outdoor were healthy and the ones raised indoor were infected by pathogens. So they came up with the conclusion of a little dirt is good for you.
Background Questions:
1. What is an allergy?
An allergy is an unusually high sensitivity to some substance.
2. What are some common symptoms of an allergy and how are they caused?
The common symptoms are a runny nose and watery eyes.
3. Describe the role of histamines in the allergic reaction.
Histamines is a chemical that your body releases when you have an injury or need to fight allergens. People sometimes needs to take antihistamine for allergies.
4. What is anaphylactic shock and what can it result in?
Anaphylactic shock is when someone has a severe allergy like peanuts or bee-sting venom. People in anaphylactic shock can result in swelling, breathing difficulty, and sometimes death.
Article Questions:
o Describe the hygiene hypothesis and how it relates to the immune system.
The hygiene hypothesis describes that a little dirt is good for your immune system.
o Describe the set-up of the study that Kelly and her colleagues did involving piglets.
They had two groups of pigs. They raised one group indoors one group outdoors, and another group in isolation with antibiotics inserted into them daily. They were testing to see which group would be healthier after 50 days.
o What were the results of the study? Be sure to explain the difference in beneficial bacteria vs. harmful bacteria in each of the pigs groups.
As they expected the group that was raised outdoors had more bacteria. However, the bacteria in the group that was outdoor had healthy bacteria and the groups that were indoors and in isolation had a great amount of pathogens.
