Experimental design. 32 female BALB/cJ mice at weaning were randomly divided into two groups fed either a standard control diet or a xylooligosaccharide (XOS) supplemented diet. After 33Â days, the mice were sensitized with 0.8% oxazolone before they were challenged ten times with 0.4% oxazolone solution on the right ear. The mice were euthanized after the last challenge and sampled for further analyses.
