  1. Denver School of Nursing – General Education Classes Lecture / Laboratory : Monday 10:00 am – 2:24pm Lecture: Tuesday 4:30pm – 6:30pm Instructor: Lisa Johansen, PhD Microbiology BIO 205Microbiology with Lab

  2. Microbiology When you see the word microbiology… What do you think of??

  3. Microbiology What is your connection to microbiology?? Work? Home? Health?

  4. Chapter 1The Science of Microbiology

  5. The Scope of Microbiology • Six subgroups • Bacteria • Archaea • Algae • Fungi • Protozoa • Viruses • Helminths **

  6. Brief History of Microbiology • 1674 Leeuwenhoek: sees microorganisms • 1796 Jenner: vaccine for smallpox • 1847 Semmelweiss: cause of childbed fever • 1859 Pasteur: disproves spontaneous gen. • 1865 Lister: introduces antiseptic technique • 1876 Koch: pure culture on agar • 1892 Iwanowski: discovers viruses • 1894 Ehrlich: selective toxicity • 1929 Fleming: discovers penicillin • 1977 Woese: classifies archaea

  7. Animalcules • Made his own microscopes • Antony van Leeuwenhoek • Looked at everything he could • White matter from his teeth

  8. Edward Jenner and Immunity • Observation: • Dairymaids who had mild cowpox infections were protected from smallpox • Hypothesis • Cowpox infection provides protection against smallpox • Experiment • Inoculated boy with cowpox fluid and later challenged with smallpox fluid • Result • Boy did not get smallpox

  9. Childbed Fever • Wash your hands! • IgnazSemmelweis • Medical students were bring disease from the morgue to the women’s clinic

  10. Spontaneous Generation • Life is formed from inanimate objects • Fruit flies!!!

  11. Spontaneous Generation • Louis Pasteur • Used swan-neck flask • Boiled broth • Open to the air • No growth unless broth was washed into the curved neck

  12. Aseptic technique • Against infection via phenol • Joseph Lister • How good is the mouthwash though?

  13. Germ Theory of Disease • Koch’s Postulates • Microbes present in samples of diseased animal • Grow organism in pure culture • Inject healthy animal with cultured cells • Animal develops same disease

  14. Viruses are discovered • Smaller than bacteria - filterable • Dmitri Iwanowski and MartinusBeijerinick • Tobacco mosaic virus

  15. Selective Toxicity • Chemotherapy • Paul Ehrlich • Magic Bullet Theory

  16. Penicillin • The birth of antibiotics • Alexander Fleming • Bad lab techniques made him famous

  17. Archaea • Not just bacteria anymore • Carl Woese • Extremophiles

  18. Microbiology Today • Diagnostics • Treatments • Genomics • Epidemiology • Emerging diseases • Bioremediation • Environment micro / microbial ecology • Green fuels • Bioterrorism • Bioengineering • Agricultural microbiology • Industrial microbiology

  19. Six subgroups • Bacteria • Archaea • Algae • Fungi • Protozoa • Viruses • Helminths ** Chapter 10 meet the microbes!

  20. Classification systems and names Kingdom

  21. Writing names properly binomial nomenclature genus species Escherichia coli orEscherichia coli E. coli orE. coli

  22. bacteria = binomial nomenclature plus genus species strains E. coli K12 E. coli ML30 E. coli 0157:H7

  23. How we classify - methods - old

  24. How we classify - Dichotomous key - an oldie but goodie

  25. How we classify - methods - new molecular biology / genetics

  26. Molecular biology and identification

  27. The Prokaryotes - Ch. 11 Archaea Bacteria

  28. Prokaryotes: Homework • Chose 5 bacteria (total) from different 5 different phyla (Ch. 11) and describe: • habitat - where is it normally found? • shape (morphology - what does it look like under the microscope) • pathogenesis (does it cause disease? if so how?) • three interesting facts (not covered above) • think medical or environmental importance • unique features • include a picture of the organism • This must be a PowerPoint presentation. • This is part of your weekly presentation grade. • Due 1/14/13 @ beginning of class - on a thumb drive or email to me.

  29. Eukaryotes and Helminths and Arthropod vectors Chapter 12

  30. A few eukaryotes to know about: Fungi macroscopic microscopic

  31. Eukaryotic cells - Fungi heterotrophic saprobe

  32. Eukaryotic cells - Fungi yeast colonies mycelium spores

  33. A few eukaryotes to know about: Fungi

  34. Fungal diseases : thermal dimorphoism

  35. Mycoses = fungal infections thrush ringworm / tinea athletes foot / tinea Cryptococcus Aspergillus
