1. Intro (I) Flashcards
Composition of fungal capsule
Polysaccharides
Function of fungal capsule
Antiphagocytic
Virulence factor
Fungi that has capsule
Yeasts (Ex: Cryptococcus neoformans)
Provides shape and rigidity to the fungal cell; for osmotic protection
Cell wall
Composition of the fungal cell wall
- Polysaccharides (90%)
- Chitin
- Proteins and glycoproteins (10%)
Part of fungal cell wall that mediates attachment to host cells
Surface components of the cell wall
Composition of fungal cell membrane
- bilayered phospholipids
- sterols (ergosterol)
Functions of the fungal cell membrane (3)
- protects cytoplasm
- regulates intake of nutrients
- facilitates capsule and cell wall synthesis
Filamentous, tubular growth
Hyphae
Cross-walls in the hyphae
Septa
Mass/mat of hyphae, mold colony
Mycelium
Obligate hyphae
Molds
Unicellular form of a fungi, budding
Yeast
Process of reproduction by yeasts
Budding
Fungi that have 2 growth forms which develop under different conditions
Dimorphic fungi
Fungi that has a known sexual stage
Perfect fungi
Fungi that does not have a known sexual stage
Fungi imperfecti
Reproductive structures produced by an asexual mode
Conida
Reproductive structures produced sexually; the asexual reproductive cells of the zygomycetes
Spores
The asexual reproductive cells of the zygomycetes
Spore
Structure that supports conidia
Conidiophore
Conidiophore produced by annelids
Annelloconidia
Conidiophore produced by phialides
Phialoconidia
Conidiophore produced from pores
Poroconidia
Saclike structure where sporangiospores are produced (Zygomycetes)
Sporangium
3 types of fungal asexual reproduction
Arthroconidia

Basidiospore
Club-shaped reproductive structure where Basidiospores develop
Basidium
Following meiosis of Basidiospores, how many meiospores develop?
4 meiospores on the surface of the club-shaped Basidium
Phylum that produces Basidiospores
Phylum Basidiomycota
Order that produces Zygospores
Order Mucorales
Round, thick-walled sexual spore produced in a saclike structure by fusion of two hyphal tips
Zygospores
Fungal infections
Mycoses
2 most common mycoses
Candidiasis
Dermatophytosis
