Training for 9 weeks reduces Listeria-induced inflammation measured by bioluminescence imaging. Control mice and mice trained 9 weeks before infection (n = 4 mice per group) were challenged i.v. with 1.7 x 10⁴ CFU L. monocytogenes. One day and 2 days post infection, inflammatory levels were measured by luminol-generated bioluminescence using an imaging system. (A) Quantification of bioluminescent signals. Each dot represents a mouse. Lines connect results obtained from one animal analyzed 1 and 2 days post infection (p.i.). (B) Representative images of control and trained mice analyzed 2 days p.i. displayed as an overlay of luminescent and X Ray modalities. Control versus trained at day 1 and day 2: P = 0.052 and 0.062, respectively.
