Hypersensitivity scores of intraperitoneally sensitized (IP) mice. Hypersensitivity symptoms were scored one hour after last challenge with CMP. Each point represents an individual mouse. Values are means, n = 6 per treatment. CTL-: PBS, control mice; CTL+: CMP sensitized mice; LGG1: CTL+ mice supplemented with LGG for 5 weeks and LGG2: CTL+ mice supplemented with LGG for 4 weeks. Means with different letters differ, P ≤ 0.05.
