Microbiology Flashcards
1
Q
Candida auris susceptibility
A
Highly fluc-R, variably vori- and ampho-R, rare echinocandi n resistance (anidula MICs lowest). Sensi testing recommended

A
3
Q
Daptomycin resistance mechanism
A
dltA dysregulation - change techoic acid component of cell wall

Q
hVISA definition & detection
A
S. aureus isolate with a susceptible vancomycin MIC but with a small subset of colonies with an intermediate MIC (small-colony variant). No molecular diagnostic methods can detect hVISA. hVISA is identi ed through population analysis pro- le-AUC.
