Micro Test 1

  1. What is a microbe?
    An organism too small to see without magnification
  2. What are the 5 categories of microbes?
    Bacteria, fungi, protozoans, algea and viruses
  3. List the major roles of microbes?
    Decompose organic waste, produce fermented food, produce chemicals, aide in agriculture, synthesize vitamins in the body, maintain chemical cycles
  4. What is bioremediation?
    Any process that uses microorganisms or their enzymes to return the environment altered by contaminants to its original condition. Ex: clean up toxic waste and sewage
  5. What is genetic engineering?
    Produce products used in manufacturing such as cellulose and treatment such as insulin or human growth hormone
  6. What is gene therapy?
    The use of a virus to insert a missing gene or replace a defective gene
  7. Who was the first person to see cells?
    Robert Hooke in 1665 while observing plant tissue
  8. Who was the first person to see living microorganisms?
    Anton Van Leewenhock saw "animalcules" in 1673
  9. What is the cell theory?
    All living things are made of cells
  10. What is the theory of biogenesis?
    All cells arise only from preexisting cells
  11. What is spontaneous generation?
    The theory that living organisms arise from non-living matter. Disproved by experiment by Pasteur
  12. How did Louis Pasteur prove that air does not create microbes?
    Put broth in special S-shaped flasks to trap microbes and then boiled to kill microbes and new organisms didn't pop up into existance.
  13. What are aseptic techniques?
    Prevent contamination by unwanted mircroorganisms such as flame steralization
  14. List some innovations that came about during the golden age
    Fermentation, pasteurization, germ theory of disease, koch's postulates, vaccination, chemotherapy
  15. What is the difference between synthetic drugs and antibiotics?
    Synthetic drugs are produced entirely from chemical reactions in a lab. Antibiotics occure naturally
  16. What is bacteriology?
    The study of prokaryotes, including bacteria and archea
  17. What is mycology?
    The study of fungi
  18. What is parasitiology?
    The study of protazoa and worms
  19. What is immuniology?
    The study of hosts defenses to a pathogen
  20. What is virology?
    The study of viruses
  21. What is your normal microflora?
    Bacteria that inhabit the interior and exterior of our bodies without causing harm. They are good.
  22. What are some of the body’s natural defenses to disease?
    Skin, mucous membranes, cilia in repiratory tract, stomach acids, immune system.
  23. What is the difference between an infectious disease and an emerging infectous disease?
    An EID is a new or changing disease, infectious diseases already exist.
