Challenge survival following intradermal immunization^a

Treatment group	No. of survivors/total no. of mice challenged with strain:
	K96243	NCTC 4845	576
DC + CpG in culture	9/10	7/10	7/10
DC + CpG adjuvant	7/10	6/10	6/10
Control ODN	3/8	2/8	3/8
DC only	2/10	1/10	2/10
Naïve	0/8	0/8	0/8

^aImmunization was performed with DCs pulsed with heat-killed B. pseudomallei K96243, with or without CpG ODN treatment. Challenge was performed with approximately 10⁴ CFU strain K96243, NCTC 4845, or 576 by the intraperitoneal route and survival at day 42 was recorded.
