Bacteria Exit Ticket Part 4 - Antibiotic Resistance

Posljednje ažuriranje 5 months ago

24 questions

What is a biofilm primarily composed of?

Only bacteria

Microorganisms (bacteria) and an extracellular matrix (slime)

Just human cells

Only DNA fragments

What are the parts of a biofilm?

bacteria

"slime" - polysaccharides made by the bacteria

human cells

antibodies

Where are biofilms commonly found?

anywhere that is moist

On clean surfaces

Only in laboratories

Only in dry area

What purpose do biofilms serve for bacteria?

allows bacteria to travel to new environments

Oxygen production

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

How do biofilms contribute to antibiotic resistance?

Reduce genetic mutations

Accelerate drug metabolism

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

Which environment promotes biofilm formation?

Open air

Dry and sterile conditions

Moist and nutrient-rich areas

High UV light exposure

Biofilms are typically easy to remove permamently from surfaces

true

false

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

True

False

Obavezno

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

True

False

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

inactivate the antibiotic by using their enzymes

stopping the uptake of the antibiotic into their cells

pumping out the antibiotic using an efflux pump

altering the target of the antibiotic by creating a modified drug target that "grabs" onto the antibiotic

Obavezno

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

good luck

many mutations

bacteria copying and sharing plasmids with each other

resistant bacteria conjugating with other bacteria in their population

Obavezno

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

The resistant bacteria reproduce successfully and the amount of resistant bacteria increases in the population
A population of resistant (or mostly) resistant bacteria has been created.
Resistant bacteria frequently share antibiotic resistance genes by conjugation - this makes antibiotic resistance spread even faster!
Most of the bacteria are killed - the resistant bacteria are not!
An antibiotic enters the environment of a population of bacteria.
The resistance bacteria are “selected for”. They survive to reproduce...
Some mutations (rarely) may allow a bacterium to RESIST (fight off) an antibiotic.
Mutations - random mistakes in copying bacterial DNA as bacterium gets ready for binary fission (to divide)

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

a strain of bacterium that is resistant to several or many antibiotics

a bacterium that is able to make its own antibiotics

a bacterium that has the ability to reproduce very quickly

a. A mold that had killed bacteria around it

b. A new type of bacteria

c. A chemical reaction between two substances

d. A virus that infected bacteria

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

a. It can cause antibiotic resistance in bacteria

b. It can lead to allergic reactions in patients

c. It can be expensive for patients

d. It can have negative side effects on the immune system

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?

a. 5 days

b. 7 days

c. 11 days

d. 14 days

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?

a. It is highly effective and recommended

b. It can help relieve symptoms temporarily

c. It is useless and can make matters worse

d. It can prevent bacterial infections from occurring

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!

Why are farm animals fed antibiotics?

to keep them from getting sick on factory farms where they live VERY close to each other

to help the animals grow more quickly

to stop them from misbehaving

to make sure they cannot get infected by a virus

Obavezno

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

in human medicine - to fight bacterial infections

as preventive medicine in our farm animals and to help farm animals grow more quickly
