  8. Rocky Mountain Spotted Fever
    - bacteria
    - borne from
    - lifestyle?
    Rickettsia ricketsii

    arthropod bourne

    obligate intracellular parasite
  9. Leprosy
    - bacterium
    - three classifications
    • Mycobacterium leprae
    • three classifications: lepromatous, tuberculoid, borderline
  10. Anthrax
    - bacteria
    - causes what?
    - lesions
    - toxins
    • Bacillus anthracis
    • normally causes a nondescript pneumonia

    extreme lesions: eschars

    • Toxins: 
    • - Factor I: edema factor (EF)
    • - Factor II: protective antigen (PA)
    • - Factor III: lethal factor (LF)
  11. Lyme Disease
    - bacteria? 
    - borne?
    - rahs
    • Borrelia burgdorferi
    • Arthropod bourne
    • Erythemia chronica migrans (chronic migrating redness)
    • bullseye rash
  12. Blepharitis
    bilateral inflammation fo the eyelid
  13. stye
    acute infection of the glands of the eye follicle
  14. Chalazion
    infection of the Meibomian glands of the eyelid
  15. Botulism and Tetanus

    - both caused by which bacterium
    - botulism results in?
    - tetanus results in?
    - Clostridium species

    botulism: food poisoning, soil; "floppy babies"

    tetanus: spastic muscle contractions
  16. Whooping cough
    --> caused by
    --> associates with 
    --> incubation
    --> cough? 
    --> infectious factor?
    • --> Caused by Bordetella pertussis
    • --> associates with ciliated respiratory epithelium
    • --> incubation in healthy patients is 5 to 14 days
    • --> cough begins during the catarrhal stage and becomes paroxysmal
    • --> pertussis is highly contagious, 20-47% of those exposed develop infection
  17. Pertussis Toxins
    the bacteria produces multiple toxins

    • - hemaglutinin attaches the organism to ciliated cells of the upper resp. tract
    • - the tracheal cytotoxin stops cilia movement and eventually kills the ciliated cells
    • - the dermonecrotic toxin constricts the local and peripheral blood vessels
    • ( results in localized tissue and skin necrosis)
