What are cutaneous infections caused from (main fungi category)
Dermatophytes
3 types of cutaneous transmission routes
- antropophilic - human
- zoophilic - animal
- geophilic - soil
Clinical symptoms of dermatophytoses
- itching
- scaling skin patches
- Breakdown keratin for nutrients
What climate would you most likely find a subcutaneous fungal infection
tropical and subtropical
How are subcutaneous infections transmitted
Soil, through traumatic lacerations or puncture wounds (rose thorn)
How are systemic fungal infections transmitted
Through the inhalation of spores
Where to most systemic fungal infections germinate
the lungs
What is the subcategory of systemic fungal infections
opportunistic infections
Types of characteristics that help identify fungal infections
- Body infection location
- Type of person they are infection (immunodeficient)
- Geographical location
How do fungi reproduce
Via spores both sexually and asexually

Key characteristics of fungi
- Have a nucleus
- heterotrophs
- saprophytic (eat dead matter)
- parasitic (nourishment from other organism)
- No chlorophyll which means they are not a plant
How are fungi classified
by location on the body
How do fungi reproduce
Sexually or asexually via spores
