Bacteria Exit Ticket Part 4 - Antibiotic Resistance

From the videos we watched .... What are some real-life examples of bacterial misuse and/or multi-drug resistant bacteria....

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?

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?

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

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?

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?

From "Superbugs That Resist Antibiotics Can Evolve in 11 Days | I Contain Multitudes", describe how this image shows how the bacteria evolved to become more antibiotic resistant over time and what the different colors represent?

Humans just recently invented antibiotics in the last few years..

Penicillin kills bacteria by poking holes in their cell walls

Select the possible strategies that antibiotics use to kill bacteria

Antibiotics are only available and used today as prescriptions given by doctors

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!

Describe how Alexander Fleming "discovered" penicillin

Explain why the average age of a typical American increased 28 years over the course of the 20th century

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

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

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

Antibiotic Resistance - Put the following steps in order....

1. Most of the bacteria are killed - the resistant bacteria are not!
2. Mutations - random mistakes in copying bacterial DNA as bacterium gets ready for binary fission (to divide)
3. Some mutations (rarely) may allow a bacterium to RESIST (fight off) an antibiotic.
4. Bacteria frequently share antibiotic resistance genes by conjugation - this makes antibiotic resistance spread even faster!
5. An antibiotic enters the environment of a population of bacteria.
6. The resistance bacteria are “selected for”
7. The resistant bacteria reproduce easily (they do not have much competition!

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

What would cause the creation of a bacterium with a plasmid that has several or many antibiotic resistance genes?
