Relative levels of transcripts for proinflammatory cytokines in homogenates from the small (A) and large (B) intestines of infant rabbits inoculated with Peru-NT (gray bars) or Peru-NTΔflaABCDE (black bars). Homogenates were obtained 3 days postinoculation. Transcript levels were determined by quantitative real-time PCR and normalized to GAPDH cDNA levels. The results are shown as log2 difference relative to the levels measured in samples from control rabbits inoculated with buffer. Stars indicate statistically significant (P < 0.05) different values in Peru-NT and Peru-NTΔflaABCDE samples.
