Effects of LF administration on the relative abundance of bacterial genera. A and B Stacked bar charts of the 30 most abundant bacterial genera identified in the faecal content and mucosal scrapings in unchallenged piglets (A) and in F18⁺ STEC challenged piglets (B). C and D Relative abundance of bacterial genera in the mucosal scrapings of colon and ileum with PP and without PP (=ileal LP) in unchallenged piglets (C) and in F18⁺ STEC challenged piglets (D).
