Week 13 (final) Flashcards
Where do we find histoplasmosis
soil, bird, and bat droppings
What do we see on a CXR of histoplasmosis
miliary infiltrates
What is the gold standard for diagnosis of histoplasmosis
bone marrow culture
What do we see on a CXR of aspergillosis
fungus ball
What is the standard for HSV detection
culture
What dermatological finding is associated with measles (rubeola)
Koplik spots
How do we detect measles
Measles virus RNA revers transcription PCR-preferred method
What virus is associated with Mumps and how do we diagnose it
paramyxovirus
viral culture: saliva, throat, CSF, urine\
PCR: rapid diagnosis
Cytomegalovirus infects what
virus infects leukocytes
Parvovirus B19 is associated with what dermatological finding
erythema infectioussum
“slapped cheek appearance”
How do we diagnose Epstein-Barr virus (EBV) for mono
diagnosed via heterophile Ab test
- “monospot”
How do we diagnose cryptococcus
diagnosed via CSF an serum testing
What is the bacteria that causes syphilis called
treponema pallidum
Compare and contrast the 2 groups of antibodies of syphilis
nontreponemal = reagin antibody
treponemal = antibodies directed towards treponema
What tests do we run for nontreponemal (syphilis)
RPR - rapid plasma reagin
VDRL: venereal disease research laboratory
What tests do we run for treponemal (syphilis)
fluorescent treponemal antibody absorption test (FTA-ABS)
- more accurate than RPR/VDRL
What do we see on KOH testing for candida infections
budding yeast with hyphae
What test can we do to diagnose aspergillosis
blood test
Cryptococcus is spread by
bird droppings
Why would we do a bronchoalveolar lavage and what would we do it for
If nasopharyngeal keeps coming back negative yet pt presents with symptoms and we believe it’s fungal
aspergillus and pneumocystis
