TABLE 2.

Infectious content^a of R. australis in IFN-γ gene knockout mice subjected to adoptive transfer with immune or nonimmune CD8 T lymphocytes

Group no.	Adoptive transfer	103 PFU of R. australis/g of tissue from the:
		Spleen	Lungs	Liver
1	Immune CD8b	29.6 ± 1.5	17.2 ± 3.9	19 ± 0.9
2	Naïve CD8	4,814 ± 758	5,449 ± 282	2,837 ± 400
3	No transfer	2,816 ± 189	2,778 ± 379	1,996 ± 163

^aMean of two repeated experiments, ± standard deviation. 

^bImmune IFN-γ gene knockout CD8 T-lymphocyte recipients' organs contained significantly fewer R. australis PFU than the corresponding organs of recipients of naïve IFN-γ gene knockout CD8 T lymphocytes (P < 0.05) or those of mice with no transfer (P < 0.05).
