Study aid - Mycology Flashcards
- What are the fungal cell components (3example)?
a. Cytoplasmic membrane with ergosterin, cell wall build up by chitin, glucan, or cellulose
- Classification the fungi by morphology?
a. Unicellular or yeast, multicellular or mould and dimorphic
- Characterisation of the dimorphic fungus
a. They grow like moulds at room temperature and grow like yeast at body temperature
- List at least two asexual spore type.
Blastopore, conidia, arthrospore, spherule.
- What is the cultivation temperature of the fungi?
25°C and 37°C to detect the dimorphism.
- What kind of culture media can be used to cultivate fungi?
Sabouraud culture media.
- What are the content (2 example) of Sabouraud culture media?
Antifungal agents against environmental moulds, carbohydrates, antibiotics.
- What kind of diseases can be caused by fungi?
Allergic reactions, intoxications, mycosis (tissue damage of fungi).
- Classification of the mycosis?
a. Superficial, cutaneous, subcutaneous, systemic, and opportunistic mycosis.
- What kind of staining can be used in mycology? (2 example)
a. Gram-, methylene blue-, India ink-, PAS-, Gömöri-Grocott staining.
- Mode of action of the antifungal drugs?
a. Inhibition of ergosterin synthesis, pore formation on membrane, inhibition of nucleic acid synthesis, inhibition of cell division
- List three causative agent of systemic mycosis.
a. Coccidioides immitis, Histoplasma capsulatum, Blastomyces dermatitidis, Paracoccidoides immitis
- List two Candida species.
a. Candida albicans, C. tropicalis, C. krusei, C. glabrata, C. parapsilosis.
- List three causative agent of opportunistic mycosis.
a. Candida sp, Cryptococcus neoformans, Pneumocystis jirovecii, Aspergillus sp., Penicillium sp., Mucor sp., Rhizopus sp.
- List two causative agent of dermatomycosis.
