Combined from all FH sites

AmpC - Organisms that produce AmpC beta-lactamase97%
n = 31

AMPC organsims are calculated from Serratia, Providencia, Morganella, Citrobacter freundii, Enterobacter and P. vulgaris. These organisms carry inducible cephalosporinases (AmpC) that cause in vivo resistance to 3rd generation cephalosporins.

Streptococcus pneumoniae93%
n = 33
