Susceptibility interpretive criteria recognized for Enterobacterales are based on a dose of 1 gram IV q 24h. For isolates with intermediate susceptibility, use a dose of 2 grams IV q 24h in patients with normal renal function.
For Haemophilus influenzae and parainfluenzae, susceptibility interpretive criteria recognized in CLSI M100 are based on a dose of 2 grams IV every 24 hours in patients with normal renal function.
For the bacteria listed below, susceptibility test interpretive criteria are not recognized at this time:
Acinetobacter spp
Other Non-Enterobacterales
