SUBCUTANEOUS MYCOSES Flashcards
Rapidly growing, velvety, or
cottony, olive to black colony; only saprophytic Cladosporium that cannot grow above 37°C
Cladosporium carrionii
longstanding lesions that have a cauliflower like surface
chromoblastomycoses
very slow-growing, black brown, gray black, or olive gray colony
Fonsecaea pedrosoi
Rapidly growing, olive-gray to black, dome-shaped, woolly or cottony colony
Phialophora verrucosa
microscopic diagnostic feature of C. carrionii, . pedrosoi, and P. verrucosa
sclerotic bodies (muriform cells)
Rapidly growing, moist, shiny, yeasty colony that later develops black, olive, velvety mycelium; grows well at 40°C but other dematiaceous fungi do not
Wangiella dermatitidis
Moderately fast-growing, gray to black, moist, yeast-like colony with black woolly mycelium; grows at 37°C but not at 40°C
Exophalia jeanselmi
loosely organized conidial head. Branching conidiophores with chains of conidia and flask-shaped phialides also are seen.
Fonsecaea pedrosoi
telemorph/sexual form
Pseudoallescheria boydii
anamorph/asexual form
Scedosporium apiospermum
1 cause of Madurella mycetomatis
Eumycotic Mycetoma
chronic, granulomatous
infection of the subcutaneous and cutaneous tissues.
Opportunistic infections,
including nasal sinus infections, meningitis, brain abscesses, and arthritis
Eumycotic Mycetoma
sac-like cleistothecia- (ascocarp-) containing asci and ascospores, which are oval, pointed, and released when ascus rupture
teleomorph`
golden-brown, elliptoid, single- celled conidia on tips of conidiophores
anamorph
Rose gardener’s disease
nodular and ulcerative lesions along the lymph channels Inoculation from
rose thorns or sphagnum
moss
