TABLE 1.

Number of CFU after intragastric administration of CpG ODN or non-CpG ODN

Dosea	CFU (106)b
	Control	CpG ODN	non-CpG ODN
First	2.5 ± 0.8	1.5 ± 0.1	NDc
Second	2.5 ± 0.08	1.2 ± 0.04d	3.3 ± 0.05

^aMice were infected with H. pylori SS1, and 2 weeks later were given CpG ODN or non-CpG ODN or were left untreated (control). Three days after each dose mice were sacrificed, and the bacterial loads were quantified as described in Materials and Methods.

^bThe data are geometric means ± standard errors of the means for each treatment group containing eight or nine mice.

^cND, not determined.

^dP < 0.01 compared to control untreated mice.
