Question 3
3.

Where are biofilms commonly found?

Question 4
4.

What purpose do biofilms serve for bacteria?

Question 5
5.

How do biofilms contribute to antibiotic resistance?

Question 6
6.

Which environment promotes biofilm formation?

Question 7
7.

Biofilms are typically easy to remove permamently from surfaces

Question 8
8.

Does penicillin kills bacteria by poking holes in their cell walls? Watch the video ...

Question 9
9.

Look at the timeline of antibiotic research. Humans just recently invented antibiotics in the last few years.... true or false?

Question 10
10.

New antibiotics are still be researched and developed .... true or false?

Question 11
11.

According to the diagram, what the mechanisms that do bacteria use to resist (fight off) antibiotics?

Question 12
12.

How could an antibacterial resistance trait spread through a bacteria population WITHOUT the bacteria needing to reproduce?

Question 13
13.

Antibiotic Resistance - Put the following steps in order from first event to last event

  1. A population of resistant (or mostly) resistant bacteria has been created.
  2. The resistant bacteria reproduce successfully and the amount of resistant bacteria increases in the population
  3. The resistance bacteria are “selected for”. They survive to reproduce...
  4. Some mutations (rarely) may allow a bacterium to RESIST (fight off) an antibiotic.
  5. Most of the bacteria are killed - the resistant bacteria are not!
Question 14
14.

What is multi-drug resistant bacteria ("superbug")?

Question 15
15.

From "Superbugs That Resist Antibiotics Can Evolve in 11 Days | I Contain Multitudes", According to the video, antibiotics are natural substances that have been in use for billions of years. True or False?

Question 16
16.

From "Superbugs That Resist Antibiotics Can Evolve in 11 Days | I Contain Multitudes", What did Alexander Fleming observe in his lab that led to the discovery of penicillin?

Question 17
17.

From "Superbugs That Resist Antibiotics Can Evolve in 11 Days | I Contain Multitudes", What is the main concern with the overuse of antibiotics?

Question 18
18.

From "Superbugs That Resist Antibiotics Can Evolve in 11 Days | I Contain Multitudes", How long did it take for the population of E. coli on the Mega-Plate to evolve super resistance to the antibiotic?

Question 19
19.

From "Superbugs That Resist Antibiotics Can Evolve in 11 Days | I Contain Multitudes", What does the video suggest about the use of antibiotics to treat viral diseases?

Question 20
20.

Antibiotics are not only given to people, but to farm animals as well. Antibiotics are also put into many cleaners and detergents. Our environment is full of antibiotics!



Watch this video from the beginning to 5:40 in. You do not have to watch after 5:40.

Why are farm animals fed antibiotics?

Question 21
21.

According to the chart, what is the largest percent usage of antibiotics in the US?

Question 22
22.

Watch this video called "Microbiology resources - How to Measure Zones of Inhibition (ZOI)"



Then watch this short video ....




Describe & explain what is different between the bacterial growth on the 2 petri dishes below

Question 23
23.

Which antibiotic is most effective at killing this type of bacterium?

Question 24
24.

Which antibiotic (A, B, or C) is this bacterium resistant to and explain how the image allows you to figure this out?

antibodies
gives ability to reproduce with viruses
Protection from outside and access to nutrients
provides an environment where bacteria can be close to each other and share DNA by conjugation
Break down antibiotics
Shield bacteria from antibiotics from outside
allow bacteria to easily share/trade plasmids through conjugation that may have genes for antibiotic resistance
altering the target of the antibiotic by creating a modified drug target that "grabs" onto the antibiotic
resistant bacteria conjugating with other bacteria in their population
An antibiotic enters the environment of a population of bacteria.
Mutations - random mistakes in copying bacterial DNA as bacterium gets ready for binary fission (to divide)
Resistant bacteria frequently share antibiotic resistance genes by conjugation - this makes antibiotic resistance spread even faster!
to help the animals grow more quickly
to stop them from misbehaving
to make sure they cannot get infected by a virus
