MMSC438 ACTUAL TEST QUESTIONS WITH
COMPLETE SOLUTION VERIFIED
RESOURCE
●● fungi characteritics
Answer: -aerobic: NO fermentation
-grow at 22-30 C (~ room temp)
-grow at neutral pH
-prefer humid conditions
-eukaryotic cells
-many are free living in the environment (saprobes) and do not cause
disease
●● eukaryotes
Answer: fungal cells
-cell wall of chitin
-80 S ribosomes
-membrane bound organelles
-ergoserol cellular membranes
-contains nucleus (often multinucleate) and nuclear membrane
-contains DNA organized into chromosomes within the nucleus
-replicates by mitosis or budding
,-nonmotile
●● prokaryotes
Answer: bacteria
-cell walls made of peptidoglycan
-70S ribosome
-non-bound organelles
-cellular membrane not made of sterols
-no nucleus
-genetic material organised into a single nucleoid
-replicate by binary fission
-some are motile
●● fungi names
Answer: anything containing "myco" or "mycetes" indiciates fungi
●● mycoses
Answer: fungal infections
-only a small number of fungi are able to cause infections in humans
-very few of the infections caused by fungi are able to be transmitted
from person to person (usually environmental)
-infections are seen most often in immunocomprimsed patients
(oppurtunistic infections)
,●● types of fungal disease
Answer: -mycotoxicosis
-hypersensitivity: mold allergy
-colonization
-infection: can be mild to life threatening
●● mycoses classifications
Answer: fungal infections are classified according to the site of the
infection on the body
-superficial
-cutaneous
-subcutaneous
-systemic
-oppurtunistic
●● superficial fungal infections
Answer: infection of the hair, skin and nails
-infection is not invasive or destructive
-not really painful, just cause appearance issues (hyperpigmentation,
hypopigmentation)
●● cutaneous fungal infections
, Answer: infections of the hair, skin and nails
-some kind of destruction is occurring, but not life-threatening
-e.g. hair falls out, itching, nails become thick and yellowed
●● subcutaneous fungal infections
Answer: infection of deeper skin layers, muscle, connective tissue, and
bone
-usually occurs by traumatic inoculation of fungus into deeper tissues
-causes formation of progressive non-healing ulcers with draining sinus
tracts
-e.g. sporotrichosis
●● systemic fungal infections
Answer: infections of the internal organs, or deep tissues
-usually occurs by inhalation through the lungs followed by
hematogenous spread
-caused by TRUE fungal pathogens
-generalized symptoms: fever, fatigue
-potentially life-threatening infections
-e.g. coccidiodomycosis
●● opportunistic fungal infections
