  2. Multiplication of any parasitic organism within or on a host's body
    Infection
  3. Disturbance in state of health to the degree that the body cannot carry out all normal functions
    Disease
  4. Intensity of disease produced by pathogens
    Virulence
  5. Rabies viruses causes neurological damage (fatal)
    Virulence
  6. During passage through the birth canal (or C-section) it aquires
    Microbes
  7. The body has how many eukaryotic cells
    10 trillion
  8. How many microbes does the body harbor
    100 trillion
  9. How many foreign cells do we have than its own cells
    10x
  10. Do not cause disease; can be resident or transient; commensals or mutuals
    Normal microflora
  11. Always present; skin, eye, mouth, nose, throat, large intestine, urinary & reproductive system
    Resident microflora
  12. Can be present when conditions are met
    Transient microflora
  13. Stomach (too acidic), nervous system, blood muscles (too hard to reach)
    No microflora
  14. Do not usually cause disease but may do so under certain conditions
    Opportunists
  15. Opportunists if the following conditions are met
    • Failure of host's normal defenses
    • Introduction of an organism into unusual body sites
    • Disturbance in normal microflora
  16. Failure of host's normal defenses (they are Immunocompromised)
    AIDS patients
  17. Introduction of an organism into unusual body sites
    E. coli from large intestine-> wounds and burns
  18. Disturbance in normal microflora

  27. Organisms compete for the same resources; only one will obtain the required amount
    Competition (+,-)
  28. One organism captures and feeds on another
    Predation (+,-)
