TABLE 3.

Effects of IPM and CAZ on lethality for GalN-sensitized C3H/HeN and C3H/HeJ mice infected with P. aeruginosa^a

Mouse strain	Treatment (dose [mg/kg])	No. of survivors/total no. of mice (%)
C3H/HeN	Saline	5/10 (50)
	IPM (20)	8/8 (100)
	CAZ (20)	0/10 (0)
C3H/HeJ	Saline	9/16 (56)
	IPM (20)	16/16 (100)
	CAZ (20)	7/16 (44)

^aGroups of C3H/HeN and C3H/HeJ mice were injected i.p. with CAZ (20 mg/kg), IPM (20 mg/kg), or saline and were immediately inoculated i.p. with P. aeruginosa organisms (3 × 10⁶ and 6 × 10⁶ CFU/mouse, respectively); the mice were injected i.p. with 18 mg of GalN 105 min later.
