MYCOVIRO LEC Flashcards
Microscopic exam: broadly attached buds on
thick-walled yeast cells (sputum, pus, exudates, urine)
Branching hyphae bearing spherical, ovoid, or piriform
conidia(3–5 μm in diameter) on slender terminal or lateral
conidiophores
BLASTO
hyphae form chains of arthroconidia (arthrospores),
which often develop in alternate cells of a hypha
COCCIDIODOMYCOSIS
After inhalation, arthroconidia forms into spherules that
contain endospores
● Diagnostic: Spherules with endospores
COCCI
hyaline, septate hyphae bearing
microconidia and large, spherical macroconidia.
HISTO
Culture: Glucose cysteine blood agar or SDA
HISTO
Both coccidioides and histoplasma can use
COMPLEMENT FIXATION TEST in Serology.
Difference is in coccidioides is skin test.
TRUE
COCCI SKIN TEST
Yeast phase (“mariner’s wheel”) of
with multipolar budding
PARACOCCI
Translucent walled yeast cells with multiple buds
● “Mariner’s wheel” or “Mickey Mouse cap”
PARA
Gram (+) oval,
budding yeast/ elongated
budding cells in chain
(pseudohyphae)
CANDIDIASIS
Thin walled trophozoites and thick walled cysts w/ 4-8 nuclei
PNEUMOCYSTIS PNEUMONIA
Microscopic: round or ovoid,
often budding with thick
capsule
CRYPTO
Microscopic: hyphal fragments
– using methenamine silve
ASPER
Broad and aseptate, branched mycelium sometimes distorted
ZYGOMYCOSIS
Microscopic: yeast are small, oval, 24 µm in diameter
PENICILLOSIS
Rhizoids in between Sporangiophores
Absidia
