INTRO TO MYCOLOGY Flashcards
what organelles do eukaryotic cells have
nucleus and mitochondria
do eukaryotic cells do aerobic or anaerobic respiration
aerobic
what kind of pH do eukaryotic fungi prefer
neutral
def? organisms that live on dead/decaying matter
saprobes
how do saprobes get their nutrients
absorbed them from the envirmont
def? organisms that live together and both benefit
symbionts
who benefits in symbiont relationship
both
def? organisms that live together and one benefit while the other remains neutral
commensals
def? organism that benefits from the host while often harming the host
parasites
if we are exposed to a fungal infection on us what kind is that
endogenous
if we are exposed to a fungal infection around us what kind is that
exogenous
what kind of people have a high resistance to fungal infections
healthy immunocompetent people
t or f: primary pathogenic fungi can infect immunocompetent people
T
how do primary pathogenic fungi infect heathy people
evade host defenses
what kind of infection do immunocompromised people get with primary pathogenic fungi
severe infection
what kind of infection do primary pathogenic fungi cause
respiratory
def? 2 life cycle phases
dimorphism
what are the 2 phases (dimorphism) of primary pathogenic fungi
saprobic (Environment) and parasitic
when do opportunistic pathogenic fungi cause problems
when there is a disruption to the host’s defense
T or F: there is such thing as nonpathogenic fungi
F
what is the kingdom of fungi
mycota
what is the newer way to classify fungi
by phylogenetic (evolution) and unique characteristics
what is the old way to classify fungi
by reproduction
how will fungi be organized in this class
disease states
type/site of infection? cause lesion of skin and appendages (2)
superficial and cutaneous
type/site of infection? cause infections through the skin
Subcutaneous
type/site of infection? most severe, cause deep, systemic disease, in normal and immunocompromised
systemic pathogens
type/site of infection? environmental and/or normal flora that can cause disease in immunocompromised
opportunistic fungi
what are the ag presenting cells
dendritic
what kind of cells are activated by the innate response
t cells
what kind of T cell secrete cytokines to activate macrophages to attack pathogen and differentiation of other T cells
T. helper 1
what kind of T cell secrete IL-17 that recruit neutrophils to site of infection
T helper 17
how do immune system cells recognize fungal cells
cell wall sugar molecules
what group of sites of infection are brain, lungs, heart, liver, spleen, and kidney
deep mycoses
what group of sites of infection are hair, nails, skin (3)
superficial, cutaneous, and subcutaneous
T or F: a greater vol of specimen is needed to test fungi
T
T or F; fungi are fast growers
F
