  1. OPPORTUNISTIC MYCOSES

  2. OPPORTUNISTIC MYCOSIS • MOLD • ASPERGILLOSIS • ZYGOMYCOSIS • YEAST • CRYPTOCUCCOSIS • CANDIDIASIS

  3. ASPERGILOSIS • Aspergillus • Saprophyte • Recycling • Carbon & Nitrogen • Decaying organic material • 900 species

  4. ASPERGILOSIS • Opportunistic • Human & Animal • A.fumigatus • A.flavus • A.niger • Conidia 2-3 μInhalation • Nosocomial infection

  5. ASPERGILOSIS • Cystic fibrosis • Immune compromise • Atopic Asthma • Hematological patients

  6. ASPERGILOSIS • Increase • Diagnosis • Antifungal therapy

  7. ASPERGILOSIS • Allergic • Pulmonary • Cutaneous • Disseminated • Miscellaneous • Iatrogenic

  8. Allergic • Asthma • IgE & Eosinophil ( increase) • ABPA • IgE & Eosinophil ( increase) • Alveolitis • Hypersensitivity type III

  9. Pulmonary • Invasive • Lymphoma & Leukemia • Secondary infection • Invasive to vessels Infarction & Dead • Non invasive • Cavity Colonization • Fungus ball (Aspergilloma) • Hemaptosis

  10. Cutaneous • Rare • 1st • Onychomycosis • Burning • IC • 2nd • Dissemination

  11. Disseminated • Brain • Kidney

  12. Miscellaneous • Otomycosis • Keratomycosis • Sinusitis

  13. Iatrogenic • Materials • Instruments • Aero cells • Air conditioner

  14. Pathogenesis & Defense factors • Cell wall • Melanin • Catalase • Fungal metabolites • Super oxide dismutase

  15. Cell wall • Interface • Ag & Enzymes • Protection • Cell wall of Conidia • Cell wall of Hyphae

  16. Cell wall of Conidia • 2 part • Dense pigmented (out) • DHN (Dihydroxy Naphthalene Melanin) • Translucent (in) • Protection • Phagositosis

  17. Cell wall of Hyphae • Component • Β 1-3 glucan • Galactomanan • Chitin • Role • Protection (PMN) • Enzyme (catalase) • Ag (Galactomanan & β1-3 glucan)

  18. Galactomanan • Special for A.fumigatus • Serum, Urine, BAL • Monoclonal Ab

  19. Melanin • Dihydroxy Phenylalanin (DOPA) • Dihydroxy Naphthalene (DHN) • Free radicals

  20. Catalase • Hydrogen peroxide • Expression • Starvation & Sexual reproduction

  21. Fungal metabolites • Toxins • Epithelial damage • Gliotoxin • Fumagilin • Helvolic acid

  22. Super oxide dismutase • Virulence factor • Surveillance • Neu • Mac

  23. Cellular immunity • T cell very important • Gamma INF( first cytokine) • IL4, IL2, TNFα • Cystic fibrosis ABPA • Innate

  24. Laboratory diagnosis • Sampling • Sputum, BAL, Serum, Urine • KOH 10% • ELISA • Dichotomous

  25. Laboratory diagnosis
