May require contact precautions if highly resistant.
ESBLs vs. AmpC: Most ESBLs are plasmid-encoded, whereas AmpCs are usually inducible and chromosomal.
In the lab, AmpCs test resistant to cefoxitin and cefotetan.
They test susceptible to aztreonam.
SPICEM stands for Serratia, Providencia, (Indole positive) Proteus vulgaris, Citrobacter freundii, Enterobacter, and Morganella.
