Mycology Flashcards
What are the fungal cell components (3example)?
Cytoplasmic membrane with ergosterin, cell wall build up by chitin, glucan, or
cellulose.
Classification the fungi by morphology?
Unicellular or yeast, multicellular or mould and dimorphic
Characterization of the dimorphic fungus
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?
Superficial, cutaneous, subcutaneous, systemic, and opportunistic mycosis
What kind of staining can be used in mycology? (2 example)
Gram-, methylene blue-, India ink-, PAS-, Gömöri-Grocott staining.
Mode of action of the antifungal drugs?
Inhibition of ergosterin synthesis, pore formation on membrane, inhibition of
nucleic acid synthesis, inhibition of cell division
List three causative agent of systemic mycosis.
Coccidioides immitis, Histoplasma capsulatum, Blastomyces dermatitidis,
Paracoccidoides immitis
List two Candida species.
Candida albicans, Candida tropicalis, Candida krusei, Candida glabrata, Candida
parapsilosis.
List three causative agent of opportunistic mycosis
Candida sp, Cryptococcus neoformans, Pneumocystis jirovecii, Aspergillus sp.,
Penicillium sp., Mucor sp., Rhizopus sp
Which fungus can cause subcutaneous mycosis?
Sporothrix shenkii
