Infectious Disease Flashcards
Common infections with chronic steroids
Bacterial infections
PCP
Hep B or C
Common infections with azathioprine
Neutropenic infections
Common infections with CellCept
Late onset CMV
Bacterial infections
Common infections with cyclosporine or tacrolimus
Viral infections
Intracellular pathogens
Common infections in plasmapheresis patients
Encapsulated organisms
Fungal infection in neutropenic patients or those undergoing CART therapy
Invasive aspergillosis
Duration of GN bacteremia who is getting better
7 days
Timing of removal from patient care duties in a non-vaccinated healthcare worker exposed to varicella
From 8th day through the 21st day
Should you vaccinate a person who was recently exposed to varicella if they were not vaccinated previously
Yes
Bacteria that causes purpura fulminans after being exposed to dogs (bite or saliva)
Capnocytophaga canimorsus
3 mechanisms of pseudomonas antibiotic resistance
- AmpC beta-lactamases
- efflux pumps
- Outer membrane porin alterations
3 common enterobacters that can have resistance with AmpC
Enterobacter cloacae
Klebsiella aerogenes
Citrobacter feundii
Antibiotic common for UTIs that is not an inducer of AmpC resistance
Bactrim
Is culture negative status common in sepsis
Yes
Infection that causes high iron and pancytopenia with adenopathy in an HIV patient
Histoplasma capsulatum
beta lactimase inhibitor that is not effective against AmpC
tazobactam
Which is worse in terms of mortality risk, ventilator associated bacterial pneumonia (VABP) or a healthcare associated pneumonia who wound up on the vent due to severity (vHABP)
vHABP
Bacterial infection that increases HIV replication by activating kappa-B
M. Tuberculosis
Bacteria associated endocarditis and if found on blood culture, warrants workup for endocarditis
S. lugdunensis
Lactose fermenting gram negative rods
Enterobacter bacteria (e. cloacae, klebsiella pneumoniae, and E. Coli)
Lactose fermenting suggests what resistance
KPC or metallo-beta-lactimases
Antibiotics that ARE effective against KPC and metallo-beta-lactimases
avibactam or vaborbactam
Tigecycline and colistin as well but toxic to kidneys
Condition that involves the cecum and other parts of the bowel and is due to bowel inflammation in the setting of chemotherapy
Neutropenic enterocolitis (aka, typhlitis)
