  • 3. Causes
    Bacteria
    Bacillus anthracis
  • 4. How is it spread?
  • 5. Through Animals
    Humans can become infected after handling infected animals
    Breathing anthrax spores from infected products (like wool)
    Eating undercooked meat from infected animals
    (Undercooked meat)
  • 6. How is it transmutable? As a biological weapon
    Anthrax spores can be distributed
    Ex. USA 2001, anthrax spores spread through postal system via letters containing spores

  • 9. Etiology-the cause or origin of a disease
  • 10. Incubation Period

    For inhalation anthrax, anywhere from a week to 60 days
  • 11. Signs and symptoms
  • 12. cutaneous anthrax
    Raised itchy bump (resembles incest bite)
    1-2 days, develops into a vesicle (cyst)
    Develops into painless ulcer (1-3 cm diameter)
    Ulcer has black center

  • 17. Meditational widening with inhalation anthrax
  • 18. Diagnosis
    Bacterial cultures
    Measuring specific antibodies in blood
    Positive cultures are unlikely after antibiotic treatment has been started
  • 19. Pathophysiology
    -the physiology of abnormal or diseased organisms or their parts
  • 20. Anthrax is acute (of abrupt onset, of short duration, rapidly progressing & in need of urgent care)
    People can’t become immune to anthrax
    Can get anthrax multiple times
  • 21. What parts of the body are affected?
    In cutaneous anthrax:
    Skin, surrounding tissues & lymph glands
    In gastrointestinal anthrax:
    Digestive system, neck & lymph glands
    In inhalation anthrax:
    Respiratory & immune system
  • 22.
  • 23. Treatmenst
    Anthrax vaccine
    Avoiding contact w/ animals
    Don’t eat improperly slaughtered/cooked meat
  • 24. Further treatment
    Prevention after exposure:
    Antibiotic & vaccine combo
    Treatment after infection:
    60 day course of antibiotics
    Success depends on type of anthrax & how soon treatment was started
