Fungus Flashcards
What is a fungi
eukaryote that lacks chlorophyll and forms spores
Whats the major informal types of Fungi
moulds, yeasts or mushrooms
What does it mean that Fungi are chemo-organotrophic
organisms which oxidize the chemical bonds in organic compounds as their energy source
Whats contained in the cell wall
polysaccharides, often chitin or glucan
What does the cell wall do
absorb nutrients
What is the classification of fungi mainly based on
morphology
What are fungi composed of
hyphae filaments
Yeast fungi favour what habitat
unicellular
What are the three main divisions of Fungi
Basidomycetes (mould, mushroom)
Ascomytes (mould, yeast mushroom)
Zygomyctes (Mould)
ABZ
Whats the asexual spores for Basidomycetes and Ascomytes (asexual spore for zygomyctes)
Condium - a spore produced asexually by various fungi at the tip of a specialized hypha
(sporangiospore)
What is the sexual spores of the 3 main division
Basidospores
ascopores
zygospores
What are the two clinical fungal infections
Systemic
Dermatophtic
What is Dermatrophic
Fungi that digest keratin as nutrient resources and causes ringworm
i.e. attack the skin
Ringworm infection classed as
Tinea: Facei, barabae, corpusin, curin, manum, pedis,
Whats the most common systemic fungal
Candida
Examples of candida
Oral/vaginal thrush
Skin/ nail infections
Most abundant candida
Candida albicans
candida tropicais
candida glabrata
If you are immunosuppressed what happens
more likely to get candida infection
Causes of immunosuppression
Cancer therapy, reduces immune system
Introduction of antibiotic as decreases competition as gets rid of gut flora
The fungal infection of Aspergillosis causes what diseases
simple asthma
aspergillosis
How does the infection of aspergillosis occur
inhalation of conidium (a sexual spore)
What are the main diseases of Cryptococcus
meningitis
What are the main systemic fungal infections
aspergillosis (lungs)
Candida albicans
Cryptococcus (head)
Superficial mycoses (feet)
