1.What are the general characteristics of fungi as organisms?
1. General characteristics of fungi as organisms
1. eukarotic, multicellular (mostely)
2. ergosterol (instead of cholesterol) in membrane
3. cell wall and components*
4. metabolism is heterotrophic
5. aerobic
6. reproduce asexually/sexually-only see ASEXUALLY CLINICALLY
7. are NOT in plant kingdom
8. SAPROPHTYIC-soil dwellers, can live on dead orgnaic material
9.suspectible to our non sepcifc and specific defenses
2. factors involved in fungal pathogenesis
1. they like acidic pH
2. adherence
3. invasion
4. resistance
5. tissue injury
6. allergic rxn
Cell walls components:
1. peptidomannan
2. glucan
3. chitin
4. cellulose
5. chitosan
How many fungi cause disease in man? how mnay of those are common?
175; 30 are common
know slide 3 -chart of prokaryoties vs. eukarytes
slide 3
All fungi can act as what? meaning they don't require growth?
as allergens; fungi that cause disease have adapted or are opportunitsts.
how do you classify fungi?
on the type of sexaul spores and SEPTATION of hyphal mycelia
1. septate
2. non-septate(coenocytic)-no cross wall
Basic methods of fungal identification
a. suspect: bacteria>virus>fungi
b. scape>digest w/KOH to digest tissue & view:
i.only need to confirm that uts fungal: see micilia, sproes, yeast phase
ii. treat w/antifungals (broad spectrum)
the clinical classification of medically relevant fungi:
a. superficial
b. cutaneious>keratinolgytic
c. subcut>requires implantation, rare
d. systemic>larege expsoure,: inhalation>problematic in immunodeficient
3. opportunitstisc>imparied host defense: alteration in normal flora
Growth and morphology of fungi: yeasts vs. molds
Yeasts: unicellular, circular, repoduce by budding, resemble bacteria colonies
Molds: multicelluar; grow as hypaae(sextension of cell wall): either
a. multiple hypahe>mycelia
b. vegatitive hypahe?roots; spores here
ability to grow either asa yeast (37C) or mold (25C); most fungi--Aspergillas; allows for pathogeneisis
lab growth and diagnoiss:
1. use Sabourad's agar-sliightly acidic media that bacteria or other growth
2. state of septation & type of ascual sproes produced in mold sate
3. cab assimilationtests
4. Dual culutre at the two different temps
5. ant/ab detection, n.acid hypridcation (PCR)
asexual reproudction of fungi
via mitosis: as in budding (yeast)
1. single cell reoval and regneration (arthrocodidida)
2. generation of spores, aka condidia
3. sproe morphology the major means of funal identification**
Sexual reproduction
azygospores, ascospores, basdidiospres; cell fusion (mating) dipolidy, differention, meoisis, deipoloid or hapolid spores
