41 Cards in this Set

  • Front
  • Back
which part of a fungi name changes based on whether it reproduces sexual or asexually
genus name changes - species name stays the same
loose mucoid capsule around fungi is only important in what species
c. neoformans
the cytoplasmic membrane of fungi in includes what
1. ergosterol
2. proteins anchored by GP1
what crosslinking connection accounts for branching

rigid backbone
B 1,6 glucan

B 1,3 glucan
endogenous fungi mean the fungi is
associated with human or animal hosts e.g candida albicans
exogenous fungi refer to those fungi that are
free living, ecological niche outside of host
absorptive heterotrophs
fungi. require Carbon be spplied in organic form - grown in their own food using secreted enzymes
penetrating power
produce spores
polymer degrading enzyme
hyphal growth
"mycelial" =
colony of hyphae and spores
pseudohyphae
elongated yeast
coenocytic
aseptate - no septa in hyphae
nuclear divisions with no cell fission
conidia structures
asexual -
microconida are often infections and macroconida are good for identification
arthospores
barrel shapped w/ in hypha filament
vaccines against fungi
no
test where carbohydrate rich walls resist digestion and host cells are dissolved
NaOH / KOH mount
test which is used to reveal encapsulated yeast
India Ink
test which binds carbohydrates in fungal cell walls resulting in black color
methaneamine silver
test which binds carbohydrates in fungal cell walls resulting in red color
PAs
glyphosphate is most likely an anti-
fungal drug
the study of fungi i
mycology
study of fungal toxin is
mycotoxicology
diseases by fungi are
mycoses
compound found in fungal cell membranes not found in mammalian cell membranes
ergosterol
fungal taxonomy is based on
morphology of sexual forms
two structures that give rigidity to fungal cell walls
glucan and chitin
the outer coat of fungal cell walls that elicits Ab response is composed of
glycoproteins
the terms vegetative and aerial refer to
growth w/in versus on the surface of media
how do you distinguish fungi's "fuzzy" colonies
morphology of spores
four clinical categories of fungal infections
1. superficial
2. cutaneous
3. subcutaneous
4. systemic
the most importatnt acquired immune defense mechanism for inhibiting fungal infections
CMI
do fungi have true nucleus
yes - they are in the eukarya domain
the part of the fungi cell wasll that allos the wall to expand and contract and prevent lysis
glucan polymers
high mannose type
the cell wall glycoproteins in fungi
Antibody response to fungi is directed against
carbohydrate proteion of glycoproteins in fungi
candida albicans is part of the normal flora of
the GI tract
which are more tolerant to acid, fungi or bacteria
fungi
asexual spre
conidia
the most common fungal infections are caused by
dermatophytes

originated in soil but probably now just inhabit humans. they utilize dead cornified appendages of host
these types infections usually take a while to develop as fungi is adapting from soil saprophyte to the host. usually happens via traumatic implantation
subcutaneous infection
primary fungal pathogens
in non-immunocompromised host
inhaled from enviroment at spore
grow in humans as yeast
person to person transmission does not occur
e.g yeast infection?
one manifestation fo the CMI response to fungus is
granuloma formation
