Downmodulation of Vaccine-Induced Immunity and Protection against the Intracellular Bacterium Francisella tularensis by the Inhibitory Receptor FcγRIIB

Table 2

Summary of adoptive transfer survival studies.

Group	Donor	Immunogen	Recipient	Percent protection	Mouse number	Statistical comparison	Significance ( value^a)
A	WT	PBS	WT	6.67	= 15
B	KO	PBS	KO	26.67	= 15	A versus B	= 0.3295
C	WT	iFt	WT	53.33	= 15
D	KO	iFt	KO	62.5	= 16	C versus D	= 0.7224

The values were determined by performing a contingency table analysis and two-tailed Fisher’s exact test on survival at day 21 after challenge.
