1
Except for disease caused by ___, humans are resistant to infections caused by fungi.
dimorphic fungi
2
Classification of Fungi based on Appearance of Colonies
moist, creamy, opaque, pasty colonies
yeasts
3
Classification of Fungi based on Appearance of Colonies
– fluffy, cottony, woolly or powdery colonies
Mold or Filamentous fungi
4
– exhibit either a yeast and filamentous forms
Dimorphic fungi
5
– when dimorphism is temperature dependent
Thermally dimorphic fungi
6
Thermally dimorphic fungi produce a mold form at what temp
25C – 30C
7
Thermally dimorphic fungi produce yeast form at what C
35-37C
8
– fungi that have more than one independent form or spore stage; not temperature dependent
Polymorphic fungi
9
4 Phyla
-includes organisms that produce sparsely septate hyphae
Zygomycota
10
Zygomycota
-asexual reproduction by ?
-sexual reproduction by ?
sporangiospores
zygospores
11
what phyla
ex. are Rhizopus, Mucor, Rhizomucor, Absidia, Cunninghamella
Zygomycota
12
what phyla
filamentous
produce true septate hyphae
ascomycota
13
asexual repro of ascomycota
conidia formation
14
sexual repro
ascopore
15
2 forms of ascomycota
teleomorph and anamorph
16
what phyla is ubiquitous in nature
ascomycota
17
– fungi that have different asexual forms of the same fungus
*Synanomorphs
18
sexual reproduction of basidiomycota
basidiopores
19
plant pathogens; rarely cause disease in humans
basidiomycota
20
-includes the smuts, rusts mushrooms, Cryptococcus neoformans complex
basidiomycota
21
– teleomorphic form of Cryptococcus neoformans
*Filobasidiella neoformans
22
– lack a sexual reproductive cycle
-asexual reproduction through conidia
4. Deuteromycota
23
also called fungi imperfecti
Deuteromycota
24
dimorphic fungus; has not been assigned to any phylum so it is placed in the order Incertae sedis
Blastomyces dermatitidis –
25
in which order is Blastomyces dermatitidis assigned
Incertae sedis
26
classification of fungi based on type of infection
superficial or cutaneous
deep or systemic
subcutaneous
opportunistic
27
-involve the hair, skin, or nails without direct invasion of deeper tissue
superficial or cutaneous
28
mycoses which all infect keratinized tissues
superficial or cutaneous
29
– causes infection to the subcutaneous tissue only (no dissemination to other sites)
Subcutaneous mycoses
