Transcript Cyotus Immunus streptococcus

Bacterial Infection:
Cyotus immunus
streptococcus
Today we will study an
INFAMOUS (yet fictitious)
bacterial infection!
Bacterial Infection:
Cyotus immunus
streptococcus
Upon examination, we find that
our patient was infected with
Cyotus Immunus streptococcus!
Antibiotics, STAT!
Bacterial Infection:
Cyotus immunus
streptococcus
Phew, we caught it
in time! The bacteria
have begun to die off.
Bacterial Infection:
Cyotus immunus
streptococcus
Our patient reports that
he is feeling a little
better!
Bacterial Infection:
Cyotus immunus
streptococcus
We check in on the
patient and find that
he is almost better.
Bacterial Infection:
Cyotus immunus
streptococcus
Our patient reports
A full recovery!
Or is it…
Now what happens???
Let’s have the patient
back for a follow-up.
Bacterial Infection:
Cyotus immunus
streptococcus
Our patient reports
a scratchy throat.
Didn’t the antibiotic
kill the bacteria?
Bacterial Infection:
Cyotus immunus
streptococcus
Oh no! Our patient
says that he feels worse…
Bacterial Infection:
Cyotus immunus
streptococcus
Our patient says that
the symptoms have
returned!
Bacterial Infection:
Cyotus immunus
streptococcus
Our patient is in
complete re-lapse!
What happened?!
Let’s put the patient back on the
antibiotic
treatment and see what happens.
Bacterial Infection:
Cyotus immunus
streptococcus
Nothing seems to have
happened yet…
Bacterial Infection:
Cyotus immunus
streptococcus
Still nothing…
Let’s give it some
more time.
Bacterial Infection:
Cyotus immunus
streptococcus
Hmmm…nothing seems
to be happening…
Our patient is anxious
to get better!
What went wrong?!

Let’s look at some animals that have
been well suited to their environment.
Animals with unique
characteristics:
Meet the Peppered Moth
It is native to
England. This
was the dominant
color variety in
the 1800s.
Meet the Peppered Moth
It also comes in black.
Can you spot the
white moth?
Meet the Peppered Moth
During the
Industrial Revolution,
the black became
dominant. Can
you see the white
moth now?
Here are your moths! Color them all the same color.
Make sure that they are all the
same color.

Survived
Questions:
1. What happened to the moth population over time?
2. Which color survived the best? How does this activity translate to
bacterial antibiotic immunity?
3. Why is it a good idea to be responsible with antibiotics?
