1

Composition of fungal capsule

Polysaccharides

2

Function of fungal capsule

Antiphagocytic
Virulence factor

3

Fungi that has capsule

Yeasts (Ex: Cryptococcus neoformans)

4

Provides shape and rigidity to the fungal cell; for osmotic protection

Cell wall

5

Composition of the fungal cell wall

- Polysaccharides (90%)
- Chitin
- Proteins and glycoproteins (10%)

6

Part of fungal cell wall that mediates attachment to host cells

Surface components of the cell wall

7

Composition of fungal cell membrane

- bilayered phospholipids
- sterols (ergosterol)

8

Functions of the fungal cell membrane (3)

- protects cytoplasm
- regulates intake of nutrients
- facilitates capsule and cell wall synthesis
