    vaccine
  3. When a bacterial infection does occur, ___ can be used to fight the disease.
    antibiotics
  4. An unknown disease that appears in a population for the first time or a well-known disease that suddenly becomes harder to control is call an _____.
    Emerging Disease
  5. Disease causing forms of proteins.
    Prions
  6. One way bacteria can cause disease is by breaking down and damaging ____ of the infected organism.
    cells or tissue
  7. Bacteria can also cause disease by releasing ___ that harm the body.
    toxins
  8. A ____ is a disease-causing agent.
    Pathogen
  9. One way to control bacterial growth is by subject the bacteria to high temperatures during a process know as _____.
    sterilizations by heat
  10. A ____ is a preparation of weakened or killed pathogens or inactivated toxins thatcan prompt the body to produce immunity to a disease.
    vaccine
  11. What organs do the bacteria that cause tuberculosis typically damage?
    Lungs
  12. What are antibiotics?
    A group of drugs used to block growth and reproduction of bacterial pathogen.
  13. How are the causes of tuberculosis and diptheris similar? How are they different?
    The causes are both taken into the body through lungs/mouth, and both break down tissue or release toxins
  14. Describe the similarities and differences of antibiotics and disinfectants?
    Both stop spead of bacteria, antibiotics don't harm host cell. Disinfectatnt can't ingest, made to sterilize.

    Most bacteria can't survive in warmer temperatures. (100 degress C.)
  16. Bacterial Control Method.

    Putting milk in refrigerator
    Safe food storage
  17. Bacterial Control Method

    Using bleach to clean a countertop
    disinfectant
  18. Bacterial Control Method

    Using boiling water to clean dishes
    sterilization by heat
  19. Bacterial Control Method

    Washing Hand.
    physical removal
  20. Bacterial Control Method

    Boiling Soup.
    Safe food processing
  21. What are some human disease caused by viruses?
    common cold, influenza, chicken pox, AIDS
  22. How do antiviral medications work? What don't they also kill host cells?
    They attack specific viral enzymes that host cells do not have.
  23. A person has a low helper-T cell count. What viral disease does he or she most likely have?
    AIDS
  24. A person has blister-like lesions on the skin. What viral disease does he or she most likely have?
    chicken pox

    true
  26. T/F

    A noninfectous disease is an unknown diseaset hat appears in a population for the first time.
    False-emerging disease
  27. T/F

    The widespread use of vaccines has led to the emergence of resistant strains of bacteria.
    false-antibiotics
  28. Slight genetic changes would be needed for the bird flu virus to become infectous to humans.
    true
  29. Scrapie is most likely caused by pathogens know as viroids.
    False-prions
  30. RNA viruses hav shown an ability to evade antiviral drugs. How do you suppose this is possible, when viruses are not alive? How may the reproductive methods of viruses help the process?
    Viruses may be able to adapt to changes from generation to generation. It replicates very quickly.
  31. What are the three different bacteria shapes?
    • bacilli -rod shaped
    • spirilla- spiral and corkscrew shaped
    • cocci-spherical
