Glycosylation of gastric mucins from H. suis-infected and noninfected pigs. a Relative abundance (%) of each of the identified glycan structures among H. suis-infected and noninfected pig gastric mucin samples. The full list of identified glycans is available in Supplementary Table 1. b Distribution of common and unique mucin glycan structures in noninfected and infected pig groups. c Number of glycan structures identified in individual gastric mucin samples isolated from noninfected and infected pigs. d H. suis infection-associated alterations in the relative abundance of terminal epitopes on pig gastric mucins. Many of the structures are branched, leading to that the sum of the terminal structures is above 100%. The relative abundance of fucosylated and acidic glycan structures increases, whereas that of the galactose-terminating glycan structures (including Galβ1,3GlcNAc) decreases with infection. Statistics: *p < 0.05, **p < 0.01, two-way ANOVA, data are plotted as mean ± SEM
