Pathogen Notes

Pathogen Foldable
14
Homework

Research any disease and find out
the following:
What type of pathogen it is caused by
 What the symptoms are
 How can it be treated
 Any other info about it/picture


Find out what you have received
vaccinations for
Pathogens Cause Disease

We will focus on 4 Types of
Pathogens:
 Fungi
 Bacteria
 Viruses
 Parasites
Fungi Fact Review
What
would you ask
about Fungi on a quiz?
ERT = Everybody Reads To…

We will read one paragraph
at a time
Discuss the answers to the
questions
Then take notes in the box

PARAGRAPH 1
Pathogens
Pathogen - Anything that can
cause disease or harm
 Also
referred to as
microbes or germs
 Virus, Bacteria &
Parasites are the 3
main types of disease
spreading pathogens
Types of Diseases
•
Non-communicable:
Cannot be passed from person to person
– Can be due to genetics, lifestyle choices,
or environmental factors
– EX: Cancer, ALS, Alzheimer’s, Arthritis,
Heart Disease, Diabetes
Communicable (Infectious or Contagious):
– Caused by a Microbe entering body and
reproducing – Bacteria, Virus, Parasite
– Easily spread between individual organisms
– EX:Cold, Flu, Strep Throat
–

PARAGRAPH 2
Virus


NOT LIVING – Needs a host to
survive and reproduce
Since it is not alive, it has NO
CELLS

Very small

Vaccines used to treat

PARAGRAPH 3
Bacteria

Living organisms

Unicellular, prokaryotic


Larger than viruses, but
usually more treatable
Antibiotics used to treat
Fun Fact:Clean skin has about 20
million bacteria per square inch…
ERT
PARAGRAPH 4
Parasites

Living organisms that need a host
to survive – highly adapted to
their host

Unicellular or multicellular

Come in many shapes and sizes

Pathogen Foldable

Quickly create a foldable that contains
quick reference information for each
type of pathogen
USE YOUR PATHOGENS
FOLDABLE TO ANSWER THE
FOLLOWING ON PAGE 14:
 How are viruses and bacteria
different?
 How are parasites and viruses
similar?
 Which type of pathogen would you
consider most serious and why?

What Was A Pathogen
Again…?

Pathogens are anything that
cause disease…they are also
referred to as microbes and
germs
What Were the 4 Pathogens We
Are Focusing On Again…?
Fungi
Bacteria
Viruses
Parasites
Throw Up…I Mean
Warm Up
Turn to page 14 and make sure
your have answered the
following using your pathogens
foldable:
 How
are viruses and bacteria
different?
 How are parasites and viruses
similar?
 Which type of pathogen would you
consider most serious and why?
Pathogen Gallery Walk
 Which
disease did you
research?
 Tape
your research up around
the room so we can review all of
the diseases that were
researched!
 What
vaccinations have you
received?
Who Figures All of This Out?

An Epidemiologist
is a scientist who
studies diseases
including how they
start, spread and
how they are
treated.
Spreading
Disease…
How does it
happen…LET’S
INVESTIGATE!?
Finding Patient Zero




Each person will receive a test tube
and a syringe
You will carefully go around the
room and trade fluids with 2 other
people using the syringe
Remember who you trade with and
in what order
When completed, sit down and
write down who you traded with
first and second
Contagions


Many pathogens are also said to
be contagions
Contagions – capable of being
spread by direct or indirect
contact (in other words…contagious)

Features Kate Winslet as an
epidemiologist trying to trace back
to “patient zero”
How Do Pathogens Cause
Harm?

They can change what your cells do

Especially viruses and even chemicals
Mutagen –
something that
actually changes or
“mutates” the
genetic material of
an organism
How do pathogens spread?

4 main ways that pathogens
are transferred:
 Person to person
 Food and water
 Environment
 Animals
People to People…

Carrier – a person who is
infected and can infect
others but may not show the
symptoms of the disease
themselves
Types of Carriers
1. Symptomatic:
– they show symptoms of the disease; they are
SICK
– they are actively spreading disease particles to
others while they are sick
– May be coughing, sneezing, have runny nose
– EX: Influenza, Chicken Pox, Common Cold
2. Asymptomatic:
– Does not appear to be sick
– Can still actively spread disease to others
– EX: HIV
Food and Water

Contaminated food and water can
spread pathogens, below are a few
examples:
=
- Infected animals
- Food or water that comes from
unsanitary areas or isn’t cleaned
- Eating raw or undercooked food
Environments

Moist


Average temperatures


More ability to reproduce
Sunlight


Not too hot or too cold
Limited exposure to fresh air


A lot like water
Good for some, bad for others
Food sources

Sugars or decaying material
Animals

•
Vector – Insects and animals
that spread disease to humans
EXAMPLES:
–
–
–
Fleas – transmit bubonic plague
Ticks – transmit Lyme disease
Mosquitoes – transmit Malaria
Medicine


Antibiotics – Medicine that
prevents the growth and
reproduction of bacteria
Vaccines – A weak dose of a
virus that helps your immune
system kill the real virus later
Preventing the Spread…







Eat right, get enough rest, avoid stress
Antibacterial soaps and antimicrobial
solutions (don’t overuse)
Antibiotics (don’t overuse)
Get vaccinated
Covering our mouths when we cough or
sneeze
Avoid unnecessary contact with people,
animals or objects that could be
contaminated!
Keep studying diseases and how they adapt
and change!
Questions??
Warning…Outbreak!


Create a warning poster, warning sign, comic,
commercial jingle or brochure or any other format you
can think of warning your neighborhood about a
possible disease outbreak!
Things to include:
Name: disease (real or fictional)
 Mugshot: picture
 Description of suspect: virus, bacteria, parasite?
 Crimes: how does it attack? how does it spread?
symptoms? common victims?
 How can you prevent being infected?
 Reward???
Must be informational, but can also be silly!!

Recap




Antibiotics treat what type of
pathogen? Vaccines?
Why do we not want to overuse
antibiotics, antibacterial cleaners or
antimicrobial solutions?
Describe the job of an epidemiologist.
Why do you think that diseases that
are no longer an issue in the United
States are still a problem in other parts
of the world?
