Presentation Transcript

  1. Warm-up • Update your Table of Contents • Write your homework – have it stamped • Get your “Fungi Assignment” out to be checked

  2. 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

  3. Pathogens Cause Disease • We will focus on 4 Types of Pathogens: • Fungi • Bacteria • Viruses • Parasites

  4. Fungi Fact Review • What would you ask about Fungi on a quiz?

  5. ERT = Everybody Reads To… • We will read one paragraph at a time • Discuss the answers to the questions • Then take notes in the box

  6. ERT Paragraph 1

  7. 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

  8. 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

  9. ERT Paragraph 2

  10. 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

  11. How a Virus Attacks a Cell… • http://www.youtube.com/watch?v=Rpj0emEGShQ

  12. ERT Paragraph 3

  13. Bacteria • Living organisms • Unicellular, prokaryotic • Larger than viruses, but usually more treatable • Antibiotics used to treat

  14. Fun Fact:Clean skin has about 20 million bacteria per square inch…

  15. ERT Paragraph 4

  16. Parasites • Living organisms that need a host to survive – highly adapted to their host • Unicellular or multicellular • Come in many shapes and sizes

  18. 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?

  19. Warm-up • Update your Table of Contents • Write your homework – have it stamped • Tape your disease research to the wall around the room – MAKE SURE YOUR NAME IS ON IT! • Make sure you have answered the questions on page 14 using your pathogens foldable from last class

  20. What Was A Pathogen Again…? • Pathogens are anything that cause disease…they are also referred to as microbes and germs

  21. What Were the 4 Pathogens We Are Focusing On Again…? • Fungi • Bacteria • Viruses • Parasites

  22. 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?

  23. 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?

  24. Who Figures All of This Out? • An Epidemiologist is a scientist who studies diseases including how they start, spread and how they are treated.

  25. Spreading Disease… How does it happen…LET’S INVESTIGATE!?

  26. 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

  27. Contagions • Many pathogens are also said to be contagions • Contagions – capable of being spread by direct or indirect contact (in other words…contagious)

  28. Contagion Clip • http://www.youtube.com/watch?v=Z7yL5DFbK5A • Features Kate Winslet as an epidemiologist trying to trace back to “patient zero”

  29. 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

  30. How do pathogens spread? • 4 main ways that pathogens are transferred: • Person to person • Food and water • Environment • Animals

  31. People to People… • Carrier – a person who is infected and can infect others but may not show the symptoms of the disease themselves

  32. 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

  33. 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

  34. 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

  35. Animals • Vector – Insects and animals that spread disease to humans • EXAMPLES: • Fleas – transmit bubonic plague • Ticks – transmit Lyme disease • Mosquitoes – transmit Malaria

  36. 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

  37. 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!

  38. Questions??

  39. 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!!

  40. Examples

  41. Warm-up • Update your Table of Contents • Write your homework – have it stamped • Put your Warning…Outbreak! assignment in the basket

  42. 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?

  43. Mythbusters: Flu Fiction • How Easily Can Pathogens Really Spread?
