Effect of orally administered exopolysaccharides produced by Lactococcus lactis subsp. cremoris FC on a mouse model of dermatitis induced by repeated exposure to 2,4,6-trinitro-1-chlorobenzene

•L. cremoris FC produced phosphorylated exopolysaccharides (EPS).•The EPS consisted of rhamnose, galactose and glucose in a molar ratio of 1:1:3.•Oral administration of EPS suppressed dermatitis in allergy model mice.•The EPS showed intestinal immunological activity through Peyer’s patch cells.
