Fig. 4 — Krill oil modulated the gut microbiome in a porcine model. aTrichuris suis infection in pigs had a significant effect on various microbial alpha diversity indices, compared to in uninfected pigs. b Krill oil (KO) supplementation increased microbial richness in the porcine proximal colon, with respect to control pigs fed soybean oil (SO). c The effect of the infection (c) and supplementation (d) on gut beta diversity as shown by non-metric multidimensional scaling (NMDS) based on a distance matrix derived from Jensen Shannon Divergence. e KO had a significant impact on Firmicutes to Bacteroidetes ratios in the proximal colon microbiome. SC: uninfected pigs fed SO. SI: infected pigs fed SO. KC: uninfected pigs fed KO. KI: infected pigs fed KO. ***p < 0.001; *p < 0.05
