Evaluation of eosinophil infiltration associated with L. lactis 11/19-B1 intake in DNFB-induced mice. Dorsal skin (A) and ear (B) samples were collected at 6 h after the last DNFB application, and subsequently stained with an Eosinophil–Mast cell stain kit. The number of eosinophils in five high-power fields per slide was compared for each group. Arrows indicate eosinophils. Results are expressed as the means ± standard deviation (SD) of five determinations for each group (n = 5). Images are from a single experiment and are representative of each group. Original magnification was 400× (scale bar, 20 µm). ** p < 0.01, *** p < 0.001 by Mann–Whitney U test. L. bulgaricus (L.B).
