A, B General overview of gene expression analysis of markers for inflammation in the fundic (A) and pyloric (B) gland zone of
-infected pigs of different ages. The data are presented as fold changes in gene expression normalized to 3 reference genes and relative to a H. suis-negative control group which is considered as 1. The fold changes are shown as means with the standard error of the mean. Statistical differences were calculated using the non-parametric Kruskal–Wallis H test. *p < 0.05; **p < 0.001 significant differences between the H. suis-positive pigs and H. suis-negative pigs.
