dimorphic
spores produced by a fungal cell through multiple cell cleavage within a saclike head?
sporangiospores
a saclike head where spores form and are held?
sporangium
tubular threads that make up filamentous fungi?
hyphae
an organism that normal doesn't cause a disease but can become pathogenic under certain conditions?
opportunistic
name two types of hyphae?
1. septate 2. aseptate
colony morphology?
1. used to make beer and bread 2. reproduce by asexual budding 3. white/gooey like cream cheese
name of yeast?
Saccharomyces cerevisiae
name a pathogenic yeast?
candida albicons
name a yeast that causes endogenously (already existing on body) acquired infections?
candida albicons

conidiospores
a disease causing organism?
pathogenic
name an opportunistic fungus?
Aspergillis niger
sabouraud's dextrose agar plate is exposed to air, within a week mold is seen growing on the plate. how did the mold get there?
1. doesn't grow bacteria, so mold can grow 2. spores in the air
how do fungi differ from bacteria?
1. fungi- eukaryotic, multicellular 2. bacteria- prokaryotic, unicellular
why don't most bacteria grow on Sabouraud's dextrose agar?
1. increased pH 2. increased sugar
