Classification Of fungi and disease Flashcards
List the composition of Fungi cell wall;
Chitin
Glucans
Mannans
Lipids
Proteins
Melanin
Features of Fungi
They are:
🌻Obligate or facultative aerobes.
🌻Eukaryotic cells
🌻Reproduce sexual/asexually (or both)
🌻Heterotrophic (saprophytic/parasitic/both)
🌻Ergosterol cell membrane rather than cholesterol.
🌻Can survive with or without sunlight /oxygen.
🌻 Cell wall has certain composition like chitin,mannans, glucans, melanin, lipids, proteins.
🌻 Unicellular but mostly multicellular.
🌻 Digest food extracellulary and absorb through their cell membrane.
Which group of drugs attack the beta glucan in the cell wall of fungi
Echinocandin e.g capsofungin
What’s the name of the antifungal drugs that attack the cell membrane
Amphotericin B and
Azole group
List the function of fungi cell wall
Confers:
Shape, mechanical strength,
Prevents osmotic lysis.
The two distinct morphological stage of fungi;
Vegetative,
Reproductive stage.
What is the feature of the vegetative state
Made up of tangle of slender thread like structure called hyphae
Which phase has more conspicuous hyphae?
Reproductive phase
A mass of hyphae is called
Mycelium
Hyphae can be septate of non septate T/F
True
Another name for non septate hyphae.
Coenocytic
