You must immerse the barrel of the micropipette in fluid, when taking in liquid
true
false
Do you prefer this type of quiz or Kahoot?
I prefer Kahoot
I prefer Quizizz
I have no preference
Both are good

How are bacterial cells different from the cells of eukaryotes?
The bacteria are prokaryotes, and the genetic material is not contained in the nuclei.
The bacteria are eukaryotes, and the genetic material is not contained in the nuclei.
The bacteria are prokaryotes, and the genetic material is contained in the nuclei.
The bacteria are eukaryotes, and the genetic material is contained in the nuclei.
Select the example of an antibiotic.
vaccine
pathogen
penicillin
antibody
Select the disease which can be treated with antibiotics.
Cold
Influenza
COVID 19
Bacterial infection
Select the example of something which does not cause antibiotic resistance.
Not finishing a course of antibiotics.
Giving antibiotics to live stock (animals we eat).
Using antibiotics when we don't need them.
Finishing a course of antibiotics.
Antibiotic resistance is a huge problem because the antibiotics we have now to fight bacteria will not work. Therefore we will need to make new kinds of .......... to fight the new types of ...........
antibiotics, bacteria
bacteria, antibiotics
antibodies, bacteria
antibiotics, viruses
The rate that bacteria develop antibiotic resistance at can be sped up by:
Exposure to lower levels of antimicrobials than prescribed
2.Exposure to broad-spectrum antibiotics (which aren’t specific to a microbe)
3.Overuse of antibiotics in foods/agriculture
4. All of the above
Examples of antibiotics:
Penicillin
Tetracyclines
Neomycin
All of the above
Broad spectrum antibiotics are good because:
They Kill many different pathogenic bacteria
They are really cheap to buy
They cause antibiotic resistance
None of the above
Broad spectrum antibiotics are bad because:
They kill many different pathogenic bacteria
They are really cheap to buy
They can increase the rate of development of antibiotic resistance
All of the above
The area where bacteria cannot survive because of the antibiotic inhibits or kills it is called:
zone of inhibition
zone of prohibition
the friend zone
zone of unhappiness
People are increasing the rate at which bacteria populations are acquiring antibiotic resistance by:
taking antibiotics only when they need them
putting antibiotics into our food and environment
not sharing antibiotics with others
Which of the following is a strain of antibiotic resistant bacteria?
RSPCA
NRA
MRSA
GCSE
What can we do to reduce the rate of development of antibiotic resistant strains of bacteria
Always finish a course of antibiotics
Only take antibiotics when they are really needed
Take antibiotics whenever it is possible
Reduce the amount of antibiotics given to animals in the farming industry
This is a graph from initial infection B. Were the bacteria wiped out?
Yes
No
It's impossible to tell
People are making antibiotic resistance worse by:
Taking antibiotics only when they need them
Not finishing the full course of prescribed antibiotics
Not sharing antibiotics with others
Taking antibiotics for when they have a virus
Antibiotic resistant bacteria can
Survive
Reproduce
Pass on the resistant gene to their offspring
All of the above
When working with bactera, what is the first thing you should do?
put on gloves
wash your hands
sterilize your workspace
How many antibiotics does this bacteria seem to be resistant to?
2
3
All of them
None of them
Over time, bacteria can become resistant to antibiotics. Why can this be considered harmful for humans?
It is harmful to humans because all bacteria are bad and humans won’t be able to eat food with bacteria in it anymore.
It is harmful to humans because when we get sick from bacteria that are resistant to antibiotics we won’t have anything to help make us better.
It is harmful to humans because bacteria are only killed with antibiotics and if we don’t have antibiotics humans will get sick and die.
No antibiotic is effective because bacteria are usually resistant to any antibiotic that has been used before.
Resistance is best defined as...
An organism that is unaffected by a toxin / chemical
A bug that is stronger than a chemical
A bacteria that has the ability to digest an antibiotic
An organism that does not undergo any type of natural selection
SELECT ALL THAT APPLY: Which of the following go with "active immunity?"
It includes antibodies that come from someone else
One example is the antibodies found in a mother's breast milk
It includes the antibodies that your body makes after being exposed to an infectious bacteria / virus
One example is when vaccines cause your body to make antibodies for a certain sickness
What is a primary antibody?
Patient's antibody and initial step in ELISA
Antibody with bound enzyme
The most important antibody
a chicken antibody
Why is there an enzyme attached to the secondary antibody?
They link to the proteins used
The catalyze reactions
They provide a colormetirc indication of antigen exposure
They are used to detect DNA
Why did you need to wash the wells after every step?
To remove unbound antibodies so there will be no false results
To clean out the wells to see the color change
Because it is fun
To target bacteria that may stick to the plastic
When a positive + result occurs in an ELISA, then one could conclude that...
a + good indication of the patient's health
the antibody for the particular pathogen is present
it is a false + and no illness
an enzyme is present
bind antigen to well
add primary antibody (Ab) and wash
add secondary Ab/enzyme and wash
add substrate
The colorimetric agent in the direct ELISA changes color from ________ to ___________.
clear to blue
clear to red
blue to orange
clear to green
