Parasite burdens in spleens and livers of BALB/c mice given live or sonicated UR6 after infection with L. donovani AG83^a

Group	Priming of infected mice with 109 UR6 organisms	Parasite count (mean ± SD) in:		% Reduction in parasite burden with respect to group A in:
		Spleen	Liver	Spleen	Liver
A		(1.50 ± 0.10) × 108	(3.70 ± 0.26) × 108
B	Live UR6	(3.80 ± 1.25) × 106	(6.40 ± 0.36) × 107	97.46b	82.70b
C	Sonicated UR6	(6.20 ± 0.37) × 106	(5.71 ± 2.81) × 107	95.66b	84.56b

^aAll groups received AG83 on day 0, and splenic and liver parasite burdens were counted on day 165. Mice were primed with UR6 on days 30, 60, and 90 after infection.
