Time course of LjNIP1 and LjPT4. Relative expression of LjPT4 and LjNIP1 over the colonization time assessed by means of qRT-PCR at different time points post inoculation. The Ct values of the samples were normalized, as explained in Figure 2. The values are the means of three biological replicates, with bars representing the standard deviation.
