Figure 2.

Temporal development of porcine and bacterial gene expression profiles. Porcine data (dotted gray) is shown as mean expression relative to control animals; bacterial data (black) is shown as mean expression relative to the time group with the lowest expression. Sample sizes are given in Table 1. SEM is depicted by error bars. *P < 0.05, **P < 0.01, ***P < 0.001 (t-test or Mann–Whitney if normal distribution could not be demonstrated) relative to control (porcine) and lowest expression (bacterial). A) expression of porcine genes involved in recognition of LPS, and bacterial genes involved in LPS synthesis (kdsB and wzxE) and ompA. B) expression of porcine genes involved iron binding and transportation and bacterial genes involved iron acquisition. Note y-axis in log-scale.
