Figure 3. Gene expression changes in rabbit ileal loops infected with avirulent or virulent Shigella.

Transcriptional response at A) early (4 to 5.5 hrs) and B) late (8 hrs) time points post infection with the avirulent BS176 strain or the virulent M90T strain. The median fold induction over uninfected controls for each gene is indicated in red while symbols represent values from individual loops. A total of twelve loops from six animals obtained in three independent experiments are shown. Note the difference in scale for the early and late time points.
