Statistical analysis of data from Fig. 7^a

Treatment group		P value obtained with passive transfer of:
Treatment	M. tuberculosis infection	Serum	Cells
PBS	−	0.0011	0.4200
IL-7	−	0.1793	0.0001
IL-7	+	0.0035	0.0001
IL-15	−	0.0001	0.0014
IL-15	+	0.0001	0.0001
Nil	+	0.0001	0.0001

^aA statistical analysis was carried out by the log rank test. Transfer of serum or cells harvested from uninfected animals or animals infected with M. tuberculosis and treated with IL-7 or IL-15 (or PBS as a control) was compared with that of mice which did not receive serum or cells (Nil).
