Q1 Microbiology

  1. What did Leeuwenhoek do?
    Developed the first microscope
  2. What did Redi do?
    First to dispute the theory of spontaneous generation
  3. What did Spallanzani do?
    Discovered if you heat air, nothing will grow.
  4. What did Jenner do?
    First person to develop the small pox vaccine
  5. What did Semmelweis do?

    • Developed Rabies Vaccine
    • Pasteurization
    • Heat sterilizes instruments too
  8. What is taxonomy?
    Science of naming living organisms
  9. What are the 2 functions of Pili on bacteria?
    • To grab onto what it is attacking
    • To grab and share genetic information with other bacteria
  10. What are the 3 types of surface coating of bacteria?
    • Glycocalyx- thin (sugar)
    • Slime layer- Thicker (protein)
    • Capsule- Thickest (glyco-protein)
  11. What 2 sections of taxonomy will we be dealing with in bacteria?
    Genus and Species
  12. What does a cell envelope do?
    • Protects the cell
    • Determines if it is gram positive or negative
  13. What is an antigen?
    A protein that identifies a cell
  14. What 2 things is bacteria primarily made of?
    Cytoplasm and ribosomes
  15. What are the 3 classifications of bacterial shape?
    • Cocci- Round
    • Spirillium- Spiral
    • Bacillus- Oval
  16. How do bacterial grow?
    • Chains- Strepto
    • Clumps- Staphylo
    • Individually- no name
  17. Where is ATP made in eukaryotes?
  18. How do Bacteria make ATP?
    Glucose (Krebs Cycle)
  19. How many ATP are made from anaerobic respiration?
    • Total- 4
    • Net- 2
  20. How many ATP are made from aerobic respiration?
    • 36
    • 38 overall (with anaerobic)
  21. What are Koch's postulates?
    • The microorganism:
    • must be found in abundance in all suffering from disease
    • Must be isolated from a diseased organism and grown in a pure culture
    • Should cause disease when introduced to healthy organism
    • Must be re-isolated from the host and be identical to first infection
  22. What is Penicillin's mechanism of action? Is is bactericidal or bacteriastatic?
    • Disrupts cell wall
    • Metabolism leading to cell lysis
    • CIDAL
  23. What is Macrolides mechanism of action? Is is bactericidal or bacteriastatic?
    • Disrupts ribosome function (STOPS protein synthesis)
  24. What is Tetracyclines mechanism of action? Is it bactericidal or bacteriastatic?
    • Disrupts portion of ribosome (INHIBITS protein synthesis)
  25. What is Quinolones mechanism of action? Is it bactericidal or bacterialistic?
    • Stops nucleic acid metabolism
  26. What is Sulfonamides mechanism of action? Is it bactericidal or bacteriastatic?
    • Blocks certain metabolic pathways
  27. What is the difference between Bactericidal and bacterialstatic?
    • CIDAL- Kills bacteria
    • STATIC- Stops growth
  28. What does par focal mean?
    Feature on microscope that allow you to switch from one objective to the next without having to refocus
  29. What are the 3 types of microscopes?
    • Disecting (weakest)
    • Compound Light (More than 1 magnifier, Up to ~1000x)
    • Electron (up to 2,000,000x)
