Colonization kinetics in different organs after oral vaccination with <i>Salmonella</i> SB824 (pHR584) or SB824.

<p>Small intestines (SI), Peyer's Patches (PP), mesenteric lymph nodes (MLN), spleens and livers of five mice were analyzed for the amount of <i>Salmonella</i> (determined as colony-forming units per gram tissue; CFU/g) on days 2, 6, 14, 21 and 31 post immunization. Each experiment was performed at least twice with similar results.
