Figure 1. Decreased expression of TLR4, TLR21 and TLR2-1 genes in susceptible chickens.

Figure 1

The relative expression of TLR4, TLR21, TLR2-1 and TLR2-2 in leukocytes of susceptible (□ ---- □) and resistant (⧫——⧫) chickens at 8 h, 16 h, 24 h, 3 d, and 12 d after infection with S.enteritidis is shown. Relative values, normalized using β-actin mRNA levels and the average expression levels in both groups at 0 h, are shown. The data are means (SD shown by the vertical bars) of 6 birds (*P<0.05; **P<0.01). TPI is time post-infection.
