Pathogens Cause Disease We will focus on 4 Types of

Pathogens:FungiBacteriaVirusesParasites

Fungi Fact ReviewWhat would you ask about Fungi on a quiz?

ERT = Everybody Reads To…

1) We will read one paragraph at a time

2) Discuss the answers to the questions

3) Then take notes in the box

PARAGRAPH 1 ERT

PathogensPathogen - Anything that can

cause disease or harmAlso referred to as microbes or germsVirus, Bacteria & Parasites are the 3

main types of diseasespreading 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 ERT

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 ERT

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…

PARAGRAPH 4 ERT

Parasites Living organisms that need a host

to survive – highly adapted to their host

Unicellular or multicellular

Come in many shapes and sizes

Pathogen Gallery WalkWhich 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 personFood and waterEnvironmentAnimals

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 Carriers1. 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

A lot like water Average temperatures

Not too hot or too cold Limited exposure to fresh air

More ability to reproduce Sunlight

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!!

with a grade)16

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?

Recap

People that are infected with a disease are called something different than animals infected with a disease…

What is the difference between a contagion and mutagen and how do they relate to communicable vs. non-communicable diseases

Why is it important to know where the people you associate with have been and who they have been in contact with?

Mythbusters: Flu Fiction How Easily Can Pathogens

Really Spread?

The Rate of Spread… How quickly a disease spreads,

and size of the area it spreads to are key factors in the study of epidemiology…

Outbreak - The Cholera Story

Cholera Background Cholera is a disease that is spread by

bacteria in water or through person-to-person contact. The onset of cholera can appear with little or no warning, and include symptoms such as diarrhea, acute spasmodic vomiting and painful cramping. The victim can lose up to 5 gallons of liquid within 24 hours consequently causing severe dehydration accompanied by cyanosis, a condition in which the skin turns blue, skin also begins to pucker and become cold…death may occur in as little as a few hours.

The Cholera Story Imagine yourself in London, the year is

1849…what would your life be like?

Suddenly, people in your neighborhood begin to get sick and die very quickly. You hear your parents whispering that this isn’t the first time they have seen this type of sickness…it happened before in 1832 and nobody really knew what to do. This time however, a doctor, John Snow, comes with a new idea…

The Cholera Story He thought that if he checked the

city’s death records and mapped out exactly where people were living when they died, he might find some clues as to what was causing the disease and therefore how to stop it from spreading any further.

The Cholera Story – Mapping Death

With this idea came the birth of early epidemiology…you are now going to take on the role of John Snow and map death to find out how you can stop the spread!!

When you are done, put your completed map and analysis in the basket!

Was the cholera outbreak in London an epidemic or pandemic…why?

What were your observations/hypotheses surrounding this outbreak?

Back to Cholera… What is miasma? Do you think it is easier for an

epidemic or pandemic to occur now, or in the past

What did we gain from this outbreak, even if we didn’t realize it at the time?

Project Outbreak A disease is considered an outbreak when it

occurs in greater numbers than expected in a community or region, or during a season. An outbreak may occur in one community or even extend to several countries. It can last from days to years. Sometimes a single case of a contagious disease is considered an outbreak. This may be true if it is an unknown disease, is new to a community, or has been absent from a population for a long time. An outbreak can be categorized as an epidemic or pandemic…what areas are most likely to have an epidemic or pandemic?

continued dominance on the planet is the virus” – Joshua Lederberg, Ph.D
