Objective: KWBAT gather and evaluate evidence from text to argue the effects of a fecal transplant on the human body.
Read both of the articles for two new types of bacteria and then complete the matching activity at the end.
1. Read: Bacteria B. fragilis
2. Read: Bacteria L. reuteri
3. Completing Matching activity
Part 1: Do Now
Bacteria from the fecal transplant can fill up the space in the gut, limiting the food and space for invading harmful bacteria. One piece of evidence that supports this claim is that Patient 23’s case study showed that before the fecal transplant, the patient had low bacteria in his gut, and the bacteria included C. difficile. In week 9, after the fecal transplant, the patient had high bacteria in his gut and no C. difficile.

Question 11
11.
Explain what happens when B. fragilis is outside of the gut.
Which quote from the first paragraph best supports this claim:
L. reuteri is one of the most helpful types of bacteria for the human microbiome.
Find a quote that supports this claim.
Question 13
13.
Question 14
14.
Match the correct type of bacteria with their effect on the human body. You may have to revisit previous lessons and use the articles for this.
hints:
Patient 23😬
You just read about two GOOD bacteria types
B. fragilis
Vomiting, Diarrhea, Fever
L. reuteri
Stomach Pains, Diarrhea, Bloating
C. difficile
Produces Immune Cells
C. jejuni
Produces Mucus
What is the claim from the above statement?
In week 9, after the fecal transplant, the patient had high bacteria in his gut and no C. difficile.
Bacteria from the fecal transplant can fill up the space in the gut, limiting the food and space for invading harmful bacteria.
One piece of evidence that supports this claim is that Patient 23’s case study showed that before the fecal transplant, the patient had low bacteria in his gut, and the bacteria included C. difficile.

Use the pie chart on the left to complete this question:
How does B. fragilis bacteria in the gut microbiome affect mouse gut health?
Select all that apply.
less gut mucus
less immune cells
more immune cells
more gut mucus
Use the pie chart on the left to complete this question:
How does L. reuteri bacteria in the gut microbiome affect mouse gut health?
Select all that apply.
less gut mucus
less immune cells
more immune cells
more gut mucus
True or False: The bacteria B. fragilis can cause dangerous infections.
True
False
True or false: B. fragilis has the ability to use nearly anything as food in the human gut
True
False
How does the bacteria B. fragilis help humans?
Prevent harmful bacteria from entering the gut by taking up space in the gut.
Taking control over harmful bacteria that invade the human gut microbiome.
This bacteria does not help humans, it is only a harmful type of bacteria.
Helping the immune system produce enough immune cells to kill harmful bacteria
What two effects does L. reuteri have on the gut microbiome
Creates natural antibiotics to fight against harmful bacteria.
Protects the gut against infection.
Improves digestion of food.
L. reuteri does not have any effect on the human gut microbiome.
