ETEC colonization in CFA/I fimbriae-immunized mice. Determination of ETEC colonization in mouse spleen, liver, lungs, and kidneys subsequent to ETEC challenge at (a) 4, (b) 8, and (c) 16 hr by CFA/I fimbriae-immunized (10 μg CFA/I fimbriae + 2.5 μg CT) or PBS-dosed mice. Depicted is the mean ± SD for differences in bacterial CFUs between CFA/I-dosed and sPBS-dosed mice; *𝑃<0.05 and **𝑃<0.01.
