Cards in this deck (22)
- 1Neutropenic patients are susceptible to.. (general)pyogenic, extracellular bacteria
some opportunistic fungi - 2Define ANC<500/mm3
- 3Neutropenic fever symptomsFever and low ANC
- 4Neutropenic fever TreatmentBroad-spectrum penicillin
Piperacillin-tazobactam (most commonly used), Cefepime, Ceftaz, maybe a carbapenem
Add MRSA coverage if concern - 5Impaired CMI types of infectionsIntracellular -
~Listeria, Legionella, some mycobacteria (M. tuberculosis, M. leprae)
Viruses
~Herpes
~Certain resp. viruses (RSV. parainflu)
Fungi like endemic mycoses (histo, cocci, blasto)
parasites like toxoplasma gondii
Extracellular
~Aspergillus, Candida - 6Impaired Humoral Immunity types of infections (general)Encapsulated bacteria
S. pneumoniae, H. influenzae - 7Asplenia have high risk to... (infections)S. pneumoniae
H. influenzae
Neisseria meningitidis - 8Early onset GBSmeningitis
pneumonia
bacteremia - 9Late onset GBSmeningitis and bacteremia
- 10GBS TreatmentUsually susceptible to penicillin
- 11GBS Prophylaxis (no allergy)Penicillin G
- 12GBS Penicillin-allergic (rash)Cefazolin
Such a spaz for getting the rash - 13GBS penicillin allergic (anaphylaxis)Clindamycin
When it's serious, you call Linda for help - 14Where does GBS colonize?Lower GI & GU tracts
10-30% of pregnant women vaginas - 15How do you perform a CAMP test?Streak S. aureus down the center.
Streak GBS perpendicular to it.
W/ GBS, you would see enhanced hemolysis (CAMP test-positive) - 16Microbio of ListeriaGram positive, short, regular bacillus
Motile at 25, less at 37
Facultative intracellular - 17Listeria PathogenesisListeriolysin O
Goes from one cell to the next by coordinating actin assembly to push bacteria to cell membrane - 18Granulomatosis infantisepticaFound with early onset Listeria
Disseminated granulomas & abscesses with high mortality - 19Listeria Symptoms in Pregnant WomenFevers, chills, nonspecific symptoms
- 20Neonates Late Onset of Listeriameningitis with sepsis
- 21Listeria TreatmentAmpicillin or Penicillin G
TMP-SMX
If meningitis, need ampicillin and either TMP-SMX or gentamicin bc ampicillin is low in CSF - 22—
