Survival of immunized mice following challenge with B. pseudomallei K96243^a

Immunizing B. thailandensis strainb	% survival after challenge with B. pseudomallei at a dose (CFU) of:
	6 × 104	6 × 105	6 × 106
PBS (control)	20	0	0
CDC2721121	100	100	20c
E555	100	100	100

^aSurvival at day 35 postchallenge (n = 5 mice for each group).

^bImmunizations via the i.p. route with ∼5 × 10⁵ CFU per mouse.

^cThe median time to death was significantly increased in this group compared to that in the PBS group (P = 0.0495).
