chap 22 Flashcards
respiratory
exanthems
rashes
macular
flat, discolored
maculopapular
raised, discolored
vesicular
FLUID with sac
Bulla(e)
vesiculars larger than 0.5
pustular
elevated, PUS filled sac
petechial
reddish brown, hemorrhagic spots
purpura
small petechial coalesce
what does CPE cytopathic effects refer to
structural changes of virus
why is igM levels use to diagnose
it’s the first antibody to response
why is the absence of F peplomer significant
bc can’t form syncitia
teratogen during first ___
trimester
what type of immunity do we rely on to prevent congenital rubella syndrome
natural passive
why is there a drop in the hematocrit
because it infect inactivation of erythroid precursor cells
what type of immune response/hypersentivity occurs when immune complexes are formed
type 3
asynchronous vesicular rash
outwardly from face
synchronous
inwardly from face
what does it mean to have a life long latent infection
bc we carry the virus after exposure and virus wait for opportunity to reactivate
why can some people still get shingles after they have been vaccinated
because immune system can be weak
what other disease can smallpox vaccine protect against
monkeypox
what are M proteins
surface antigen identify different spp of Strep, provide tropism
lancefield group?
to identify different beta hemolytic streptococci
why do we still culture if the Rapid Strep test is negative
to make sure it’s accurate
What is molecular mimicry
the mimic of self molecule of the pathogen -> can lead to autoimmune
what would be the most appropriate response against common cold virus
innate response
what is a peplomer
virally associated adhesion molecule
antigenic shift
rapid change
antigenic drift
slowly change
what signs and symptoms provide a clinical basis to differentiate the “Flu” from “Cold”
fever, muscle pain
pertussis toxin A - whooping cough role
promotes lymphocytosis, sensitize to histamine, edema
tracheal toxin
vasoconstriction, necrosis to tissue
what is typical pneumonia
bacterial growing inside aveoli with inflammatory cells
atypical pneumonia
virus growing outside aveoli, squeezing -> hard to breathe
how does being cell-wall less affect the host immune response
avoid detection, phagocytosis, antimicrobial agents
what are cold agglutinins
autoimmune
how does atypical pneumonia cause damge to the lung tissue
adhere to mucous, oxygen radicals cause necrosis
what is the cause of the pneumonia signs and symptoms
chest pain, trouble breathing, dry cough
what are the risk factors for legionnaires disease
unhealthy routine, older adults
how can the plague be transmitted
through airborne drops
how is a patient treated once diagnosed with plague
isolation and antibiotics
