1. Vector:
    1) A quantity, such as the velocity of an object or the force acting on an object.

    2) An organism, such as a mosquito or tick, that spreads pathogens from one host to another

    3) A bacteriophage, plasmid, or other agent that transfers genetic material from one cell to another

    - carriers of pathogens
  2. What must happen for a pathogen to be transmitted by a mosquito vector:
    - The pathogen must migrate to the mosquito salivary gland and replicate there.

    - Only the Anopheles species of mosquito can transmit malaria

    - The female bites
  3. How do lice remain attached to their host:
    - Legs, claws, and teeth that are adapted to grasp
  4. Name a disease transmitted by flea vectors:
    • - plague
    • - typhus
  5. Name a disease transmitted by Tick vectors:
    • - lyme
    • - Rocky Mountain spotted fever
  6. Name a disease transmitted by Mosquito vectors:
    - Malaria
  7. Name a disease transmitted by lice vectors:
    - Trench fever

    - Typhus

    - Relapsing fever
  8. Name a disease transmitted by mite vectors:
    - Allergic reactin (rash/itch)
  9. How do mites directly cause disease:
    - Burrow into the skin and induce an intense allergic response.
  10. Name 2 organisms, their diseases, and the tick vectors that spread them:
    1) Dermacentor andersoni; transmitts Rickettsia rickettsit (Rocky Mountain spotted fever)

    2) Ixodes scapularis; transmitt Borreliaburgdorferi (Lyme Disease)
