NUR 3125 – INFECTION FINAL EXAM
REAL EXAM 100+ QUESTIONS AND
CORRECT ANSWERS (VERIFIED
ANSWERS) A GRADE
blocks immune response (bacterial resistance) - Answer-release surface molecules that
bind to and neutralize antibodies
fungi structures - Answer-mold, yeast, or dimorphic
mycosis - Answer-infection with a fungus
fungal infection transmission routes... - Answer-inhalation or contamination of wounds
dermatophytes - Answer-fungal infection of skin, hair, or nails
how does the fungus attach? - Answer-adhere to epithelial cells using several
polysaccharides on the fungal surface
do fungal infection pathogens produce toxins? what is the exception? - Answer-NO, but
Candida albicans is needed for the infection of mucosa
typical immune and inflammatory response to fungal infections... - Answer-cell-mediated
response with infiltration of T-cells, macrophages, and neutrophils
difficulties with dealing with fungal infections... - Answer-encapsulation and altered
antigen expression --> progressive production of pro-inflammatory cytokines -->
destruction of healthy tissue
fungal pathogens adapt to host environment
survive phagocytosis by replicating in the phagosome
protozoan infection examples - Answer-Toxoplasma gondii= causes blindness and
miscarriage
Trichomonas vaginalis= a sexually transmitted infection that triggers premature delivery
main transmission for parasitic and protozoan infections... - Answer-vectors (ex. malaria
by mosquitos, trypanosomes by tsetse fly, Leishmania spp. by sand fleas)
extracellular parasites... - Answer-attach to a tissue lining, and evolve to a more
invasive form
intracellular parasites... - Answer-reproduce within cells
parasitic infection may insert pores into intestinal cells leading to... - Answer-increased
influx of calcium, efflux of water, and diarrhea
parasites can survive immune destruction by... - Answer-invade macrophages
block recognition of pathogen antigens by binding with antibodies
block the immune response by:
secreting enzymes that degrade immunoglobulins, inactivate the complement system,
prevent antigen processing by macrophages, inhibit complement-mediated phagocyte
chemotaxis, inhibit T-cell function
basic structure of a virus... - Answer-virion (nucleic acid surrounded by the capsid)
how is an infectious virus classified... - Answer-is it DNA or RNA?
does it use enzyme reverse transcriptase for replication?
what is the most common affliction of humans? - Answer-viral diseases (ex. common
cold, cold sores, hepatitis, HIV)
virus life cycle... - Answer-attaches to the host cell via protein receptors --> penetrates
the host cell --> releases genetic information into the host cytoplasm
interferons are effective against
RNA virus life cycle... - Answer-enter the host nucleus -->
produce messenger RNA (mRNA) (new viral material).
may produce provirus DNA (retroviruses, HIV)
DNA virus life cycle... - Answer-DNA viruses enter the host nucleus --> may integrate
into the host DNA; may make mRNA
harmful effects of viruses... - Answer-inhibition of DNA, RNA, or protein synthesis in
host cells
