L-1_Prelim: Introduction to Mycology Flashcards
What is the study of Fungi?
Mycology
What is the study of fungi and their relationship to human disease?
Medical Mycology
What do you call the fungi that is considered as true pathogens?
Historically Pathogenic Fungi
What do you call the fungi that is considered as opportunistic pathogens?
Saprophytic Fungi
What are the two organisms that is under Medical Mycology?
Single-celled yeast & Filamentous molds
It is also called as superficial skin infection.
Cutaneous mycosis
It is also called as disseminated deep-seated visceral disease.
Systemic mycosis
True or False: Saprophytic fungi only affects immunocompromised host, patient with immunosuppressive infection, patient undergoing high-dose cancer chemotherapy, and people donating solid organ.
True
What do you call the hyphae produced above the surface of the agar media?
Aerial mycelium
What are the two classifications or types of fungi
Molds and yeast
- Eukaryotic
- Most fungi are saprophytic (they live on dead organic matter)
- Fungi are yeasts (filamentous) and/or molds (moist)
- Organisms that display both yeast and mold forms are dimorphic
- They are thermally polymorphic when dependent on temperature
A. 1 statement is correct
B. 2 statements are correct
C. 3 statements are correct
D. 4 statements are correct
C
Yeast = Moist
Molds = Filamentous
Yeast = Environmental
Molds = In vivo
A. 1 statement is correct
B. 2 statements are correct
C. 3 statements are correct
D. 4 statements are correct
B
True or False: Environmental saprobes lives in living material
False
True or False: Fungi that have more than one form or stage are polymorphic
True
What do you call the asexual form of fungal sporulation, also known as imperfect state?
Anamorph
It is a conidium derived from the fragmentation of specialized.
Arthroconidium
It is a fruiting structure that contains asci.
Ascocarp (ascoma)
It is a sexual spore formed within an ascus following meiosis.
Ascospore
It is a sac-like structure that contains ascospores, characteristics of Ascomycetes.
Ascus (plural is asci)
It is a sexual spore formed as an outgrowth of a basidium.
Basidiospore
It is an asexual spore formed by budding of the hyphal, pseudohyphal, or yeast cell.
Blastoconidium (plural is Blastoconidia)
It is a thick-walled resting or survival structure, also known as Chlamydoconidia
Chlamydospore
It is an enclosed ascocarp, composed of layers of hyphae that contain randomly dispersed asci.
Cleistothecium (plural is Cleistothecia)
It is a funnel-shaped structure at the apex of a phialide
Collarette
