INTRO TO MYCOLOGY TERMS Flashcards
unicellular. spheiicad to ellipsoid [3-15 tpmi
lungal polls that usually reproduca lay budding
yeasts
A fliarnentous fungus
mold
having two morphologic forms dependent on temperature
dimorphic
the diversity of fungi can be organized as what types of species?
yeasts
mold-like
mushroom and toadstool
the fungi cell wall is made of?
chitin poly N-acetylglucosamine
individual filament (small little divisions) that compose a mold colony
hypha
incomplete budding where the cells elongate but remain attached after division
pseudohyphae
A matt/ mass of hyphae growth
mycelium
Hyphae which grow above the colony surface
aerial hyphae
filaments of cells Visible mycelium (colony)
thallus
production of daughter cells like blastoconidia by separation of outgrowth o the parent cell
budding
asexual reproductive structure like microspores produced either from the transformation of a vegetative yeast or hyphae cell or from a specialized conidiogenous cell which can be simple or complex and elaborate
Conidia
conidia may be formed on specialized hyphae
examples?
conidiophores
microconidia(small) and macroconidia(large)
conidia that result from the fragmentation of hyphae cells like the coccidioides immitis
arthroconidia
a structure which asexual spores are formed by cleavage of the contents
sporangium
a specialized hypha which produces a sporangium
sporangiopores
sexual spore formed in in ascus
ascopore
a large sac filled with endospores each of which is capable of reproduction and produced by _____?
endospherules
coccidioides imitis
thick walled, round or irregular resting spores which are capable of reproducing the fungus
chlamydospores
following meiosis, four meiospores usually form on the surface of a specialized structure, club shaped basidium
basidiospores
following meiosis, a large thick wall of this term develops
zygospore
coenocytic hyphae are common with?
zygomycetes
fungi which produce microscopic spores inside special, elongated cells or sacs, known as ‘asci’
ascomycetes
a fungus whose spores develop in basidia. These include the majority of familiar mushrooms and toadstools
basidiomycetes
anamorphic fungi, fungi (kingdom Fungi) in which a true sexual state is uncommon or unknown. Many of these fungi reproduce asexually by spores (conidia or oidia) or by budding
deuteromycetes
fungi that lack sexual reproduction and are represented by an anamorph. These are identified on the basis of asexual reproductive structures
fungi imperfecti
fungi whose cell walls contain melanin which imparts a brown or black pigment
dermitaceous fungi
fungi that are nonpigmented
hyaline hyphae
name this type of mycology classification scheme
skin, hair, and/ or nails
Involves keratinized tissue or nails, hair, or stratum corneum of the skin (dermatophytes) (Tinea versicolor)
Superficial
name this type of mycology classification scheme
Involve primarily subcutaneous tissues, lymphatic vessels and
contiguous tissues. Usually acquired by trauma
Subcutaneous
name this type of mycology classification scheme
May involve any organ system and can vary from subclinical to
progressive disease. Can cause disease in healthy individuals,
the etiologic agents have a specific geographic niche
Systemic
name this type of mycology classification scheme
Fungi that are part of normal flora, or saprophytic organisms
out in the environment. Often initiated by a break in the hosts
primary lines of defense.
Opportunistic
a type of bacterial infection caused by the Corynebacterium minitissimum in which Pink to red to reddish brown, fluoresces coral red under
Woods lamp. (almost looks like Tinea cruris)
erythrasma
