  7. Fungus
    • The majority decompose plant material
    • Made up of Hyphae and Mycelium
    • 2 types that harm 1) pathogenic 2) opportunistic that attack weakened immune systems
    • spoils fruits and veggies
  8. Mycelium
    • reproductive system of fungi
    • spores
  9. Mycosis
    • Fungal infection
    • chronic because fungi grow slowly
    • 4 types
    • superficial
    • cutaneous
    • subcutaneous
    • systemic
  10. Superficial mycosis
    • skin discoloration
    • not harmful

    • not all are pathogenic
    • KOH Preps
    • examples: ringworm, body, beard, jock itch, athletes foot...
  12. Trichophyton
    • Cutaneous mycosis
    • more common in adult infections
  13. Microsporum
    • Cutaneous mycosis
    • dogs and cats get it
    • will fluoresce under UV
  14. Subcutaneous mycosis
    beneath the skin
  15. Sporothrix Schenckii
    • subcutaneous mycosis
    • Referred to as Rose Grower's disease
    • found in roses, hay, wood
  16. Systemic mycosis
    • mold
    • within the body
    • can affect multiple tissues or organs
    • enters the body through inhalation of spores
  17. Histoplasma capsulatum
    • systemic mycosis
    • 95% of causes are asymptomatic and self-limiting
    • causes chronic pulmonary disease
    • in areas of high nitrogen content such as chicken houses and barns
    • Pathogenic
  18. Coccidioides immitis
    • systemic mycosis
    • also known as valley fever
    • limited to semiarid regions like the desert SW U.S.
    • you get it by inhaling an infected arthroconidia
    • 60% of the infections are asymptomatic and self-limiting
    • Respiratory tract infections can disseminate
    • Pathogenic
  19. Aspergillus
    • mold 
    • opportunistic
    • very prevalent in the world
  20. Candida albicans
    • yeast
    • opportunistic
    • normal flora in and on the human body

    • can get in spinal fluid
    • from bird droppings
    • tested for using the Cryptococcus antigen test
  22. Lichen
    is algae and mold
  23. Algae
