fung Flashcards
all of systemic mycoses cause
pneumoniae
all sysetmic mycosis caused by
dimorphic fungi
what is dimorphic fungi
cold (20C) = mold
heat (37C) = yeast
exception to dimoprhic fungi
coccidiodes
why is coccidiodes exception to dimorphic fungi
it is a spherule (not yeast) in tissue
Treatmetn for local infection of mycosese
fluconazole, itraconazole
treatment for systemic infection of mycoses
amphotericin B
located in mississippi and ohio river valleys
histoplasmosis
small ovoid bodies within a macropahge
histoplasmosis
macrophage filled with histoplasma (smaller than rBC’)
histoplasmosis
palatal/tongue ulcers, splenomegaly
histoplasmosis
bird or bat droppings in mississisppi
histopalasmosi
diagnose histoplasmosis via
urine/serum antigen
histoplasmsos is transmitted thorough
inhalation; converts to yeast form in lungs; replicates within phagosome of macs
ulcerated lesions on tongue
histoplasmosis
impaired immunity for histoplasmsosi
AIDS; at risk for dissemination through RES system due to organisms affinity for mononuclear phagocytic cells
located in easter and central us; ohio mississippi river valley, GREAT LAKES REGION
blastomycosis
broad based budding
blastomycoses
same size as RBC
blastomycosis
inflammatory lung diseaes, can disseminate to skin/bone. on skin is papular or pustular lesions
blastomycoses
verrucous skin lesions that can stimulate SCC
blastomycoses
forms granulomatous nodules
blastomycoses
immunocompormised pt’s in blastomycoses
bone pain (lytic lesions), skin lesions, systemic symptoms, lung involvement
biopsy of blastomycoses
large round yeasts w doubly refractible wall and single broad based budd
southwestern US, california
coccidiomycosis
northern mexico, central south america, san joaquin valley
coccidiomycosis
thick walled spherule
coccidiomycosis
spherule filled with endospores of
coccidiodes
mycoses: erythema nodosum (desert bumps) or multiforme arthalgias (desert rheumatism)
coccidiomycois
coccidioodcymocis disseminates to skin/bones and causes meningitis
True
located in latin america ; central + south america
paracoccidiodomycosis
budding yeast with captain wheel formation (much larger than RBC)
paracoccidiomycosis
multiple budding blastocondia
paracoccidiomycosis
both replicate within macrophages
blastomcyosis and cocidiomycosis
