  1. Define microbiology.
    the science that deals with microscopically small living things too small to be seen with the naked eye
  2. Define bacteriology.
    study of bacteria
  3. Define virology.
    study of viruses
  4. Define mycology.
    study of fungi, molds, and yeasts
  5. Define protozoology.
    study of protozoa
  6. Define algology and phycology.
    study of algae
  7. What are the two cell types of bacteria?
    • prokaryotic
    • eukaryotic
  8. Are prokaryotic cell types single-celled organisms?
  9. Do prokaryotic cell types have distinct membrane-bound nucleus or membrane-bound organelles?
  10. Is the DNA organized into chromosomes with prokaryotic cell types?
  11. What are some examples of prokaryotic cell types
    • bacteria
    • viruses
    • cyanobacteria - blue green algae
  12. What are eukaryotic cell types?
    • everybody except bacteria, viruses, and blue-green algae
    • mammals, avians, plants, etc.
  13. What are the two groups bacteria can be divided into based on their staining characteristics?
    • gram positive
    • gram negative
  14. Why do gram positive and gram negative bacteria stain differently?
    have different cell wall structures
  15. Would you use the same antibiotics for gram negative and gram positive bacteria?
  16. Other than staining, what are the other ways bacteria can be classified?
    • bacterial shape
    • arrangement
    • colony characteristics
    • growth and reactions on different media
    • other tests
  17. What are the LVT's goals with microbiology?
    • know common diseases caused by bacterial infections
    • understand how to sample for culture, isolate, identify, and determine the best way to treat bacterial disease
    • culture and sensitivity
  18. What is culture?
    growing and identifying bacteria associated with disease
  19. What is sensitivity?
    determining which antimicrobial drug would be best to treat the specific infection that you just cultured.
