Study Notes
- Asexual spores are structures used for reproduction in fungi
Sporangiospores
- These spores develop inside a sac called a sporangium
Conidia (Condiospores)
- These spores are not enclosed within a sac
Types of Conidia
- Arthrospores are rectangular in shape
- Chlamydospores are spherical
- Blastospores form by budding from a parent cell
- Phialospores bud from the mouth of a vase-shaped cell
- Microconidia are one-celled spores
- Macroconidia are spores with two or more cells
- Microconidia and macroconidia are formed by the same fungus but under different conditions
- Porospores grow out through small pores
Pathogenic Fungi
- These are fungi that can cause diseases
Superficial Mycoses (Cutaneous Mycoses)
- These are fungal infections of the skin
Dermatomycoses
- Also known as Tinea or ringworm
- Trichophyton infects hair, skin, and nails
- Epidermophyton infects skin and nails
- Microsporum infects hair and skin
- Tinea capitis affects the scalp
- Tinea corporis affects the body
- Tinea cruris is commonly known as jock itch
- Tinea unguium affects the nails
- Tinea pedis is commonly known as athlete's foot
- Tinea versicolor causes discolored patches on the skin
Sporotrichosis
- Caused by Sporothrix schenckii
Candidiasis
- Caused by Candida albicans
- Can result from suppression of immunity
- Genitourinary tract infections include vaginal yeast infections
- Diaper rash can occur in infants
- Oral thrush is a mouth infection
