TABLE 2.

S. maltophilia strains isolated from the spleens of infected mice

Mice	Isolate	Total no. of CFU
		Median	Range
Wild type	CF1	5	4-6
	CF2	3	1-14
	N1	2	2-11
	N2	0
	N3	54a	35-93
TNFR1 null	N3	2.5b	1-100

^aP < 0.001, as determined by the Mann-Whitney test, for comparisons with the values for CF1, CF2, and N1.

^bP < 0.01, as determined by the Mann-Whitney test, for a comparison with the value for N3 in wild-type mice.
