Intro: Miscellenous Term Flashcards
sac-like structure containing (usually eight)
ascospores developed during sexual reproduction in
the Ascomycetes.
Ascus
spores (reproductive bodies
of a fungus) are formed directly from the vegetative
mycelium or from specialized hyphae.
Asexual reproduction
subcutaneous mycosis
often the result of traumatic inoculation of a
dematiaceous fungus into the skin; etiologic agents
include species of Cladosporium, Fonsecae,
Exophiala, and Phialophora.
Chromoblastomycosis
a cell or an aseptate hypha containing
numerous nuclei.
Coenocytic
a specialized branch of hypha on
which conidia are developed.
Conidiophore
pigmented, dark in color, usually
gray to black.
Dematiaceous
ability of some fungi to grow
as either yeast of filamentous stages, depending on
conditions of growth.
Dimorphic
ability of the fungus to grow on the
outside of a hair shaft.
Ectothrixic
ability of the fungus to grow and
penetrate into the hair shaft.
Endothrixic
derived from internal source.
Endogenous
derived from external source
Exogenous
organisms possessing a true nucleus
(such as fungi) as opposed to prokaryotes which do
not contain a nuclear membrane (such as bacteria)
Eukaryotes
fungal blood infection.
Fungemia
a large class of fungi with septate
hyphae in which the asexual state of reproduction is
but not the sexual state. They are also calles
Deuteromycetes and include the majority of medically
significant fungi.
Fungal imperfecti
small projections which arise from cells
of certain yeasts; indicates the onset of hyphal
formation.
Germ tube
colorless, clear
Hyaline
term generally referring to filamentous fungi.
Mold
a clinical syndrome of localized,
tumorous lesions in cutaneous and subcutaneous
tissue due to infections, often a foot, with
actinomycetes of fungi.
Mycetoma
a disease caused by fungus.
Mycoses
toxins of fungal origin.
Mycotoxins
also called zygospore, a sexual spore produced through the fusion of two unlike nuclei (class Phycomycetes).
Oospore
fungi having sexual and asexual reproductive stages.
Perfect fungi
class of fungi forming a coenocytic mycelium with stiff sporangiophores that bear
Phycomycetes
a chain of elongated budding cells that have failed to detach (not true hyphae).
Pseaudohypae
term used to describe circular or ring-like skin lesions produced by dermatophytes.
Ringworm
root-like structures.
Rhizoids
any plant organism that obtains its nourishment from dead organic matter.
Saprobes
a special aerial hypha or stalk bearing a sporangium.
Sporangiospores
a sac or cell containing spores produced asexually.
Sporangium
generally the reproductive body of fungus; occasionally, a resistant body for adverse environment.
Spores
a specialized structure that arises from a basidium and supports basidiospores.
Sterigmata
