  1. Burrito Book of Microbiology Tales of Tiny Assassins

  2. What Do We Really Need To Know? • basic characteristics • how they infect a host • what diseases they cause • how they can be stopped.

  3. How Viruses Attack Viruses and Bacteria

  4. There is a HUGE difference in their sizes. Viruses are 1/10th to 1/100,000th the size of a bacterium. Bacteria are 1/10th to 1/100,000th the size of a protist

  5. Viruses - Basic Characteristics What is a virus? A non-living container of DNA. Not a cell Must use another organism to reproduce

  6. Virus Structures and Examples

  7. How We Get Viruses ･Sneezes! ･Coughs ･Bites from infected animals or insects ･Exposure to infected bodily fluids through activities such as sexual intercourse or sharing hypodermic needles.

  8. Once a virus has found a new host…

  9. Diseases Caused By Virus Measles, mumps, rubella, polio, encephalits, diptheria, chicken pox, small pox, mono, warts, …viral pneumonia... Polio Victim …and also colds, flu, HIV, yellow fever,herpes, bird flu , hepitiusA/B and many more! Flu epidemic of 1918

  10. How do You Stop A Virus? • Immunizations • Natural antibodies • Avoid others who are infected • Wash your hands • Maintain a strong immune system Monoclonal antibody

  11. What are Bacteria? Single-celled prokaryotes with tiny flagella. • Different bacteria can “eat” everything from sunlight, to sugar to iron and sulfur, and may emit toxins as waste products. They can be found everywhere and in large amounts. 100,000 / square inch of skin; 1,000,000,000 /teaspoon of dirt.

  12. Bacteria Forms Sphere-shaped bacteria (cocci) sometimes grow in chains or in clumps like a bunch of grapes. Rod-shaped bacteria (bacilli) can also form in chains. Spiral-shaped bacteria (spirilla) can use their shape to propel themselves by twisting like a corkscrew.

  13. Diseases Caused by Bacteria • Whooping Cough･Leprosy･Tetanus･Salmonella･BotulismScarlet fever･ Ear Ache Strep throat･Cholera･DysenteryGonorrhea･Anthrax･ Diphtheria ･Syphilis･Tuberculosis Bacterial Pneumonia Leprosy Tetanus And don’t forget Septicemia!

  14. How Bacteria Invades • Coughs or sneezes! • Close contact with an infected person • Contact with feces • Cuts • Indirectly, by touching contaminated surfaces • Drinking contaminated water • Eating contaminated food without cooking it thoroughly.

  15. How Prevented/Cured/Manged Antibiotics Disinfectants Clean water Cooking meat throughly WASHING HANDS!!!!

  16. …and I’d wash carefully after wearing that meat, too…

  17. Protists • Stained Volvox and Amoebas

  18. Basic Characteristics Of Protists • Single-celled eukaryotes • Live in water • Everyone classifies differently Giardia Kelp Can live in colonies so they look big, like kelp.

  19. Sickness Caused By Protists Pfeisteria -pfeisteria dinoflagellate Malaria - plasmodium Amoebic dysentery -Entamoeba histolytica Pfeisteria dinoflagelate Most protists are benign to humans.

  20. How They Infect • Consumed in dirty water • Mosquito bites • Uncooked food

  21. How to Prevent Infection • Clean water • Insecticides, anti-malarial medicines • Cooking food thoroughly

  22. Fungi Characteristics • Eat decomposing organic material • Like moist areas • Come in many forms • Macroscopic and microscopic

  23. Mycelium and hyphae structure

  24. Sicknesses Caused by Fungi • Ringworm • Athelete’s Foot • Yeast Infection • Poisoning

  25. How fungi infect • Spores carry on the wind everywhere. • Athelete’s Foot - direct contact with fungus on surfaces • Bacteria/fungal imbalance

  26. How Prevented/Cured • Fungicides • Good hygene • Avoiding fungus-friendly surfaces • Don’t eat wild mushrooms!

  27. What’s on Tuesday’s Test? • All this info about small things that kill you: • Viruses, bacteria, fungus, protists: • What they look like, misc. important information, diseases caused by, how to prevent.

  28. What Do We Need To Know About Cells? • How to use a microscope • Cell Theory • The difference between animal and plant cells. • Role and function of the cell organelles. • Cell processes: photosynthesis, respiration, and mitosis/meiosis.
