Histologic sections of bronchioles from calves that received aerosolized bacterial lysate 24 h prior to euthanasia. At lower doses of bacterial lysate (a, calf 1, 108 CFU-equivalents; and b, calf 2, 109 CFU equivalents), the bronchioles have no or few neutrophils within their lumens. At higher doses of bacterial lysate (c, calf 3, 1010 CFU-equivalents; and d, calf 4, 1011 CFU-equivalents) there are neutrophils within bronchioles. Bar = 40 μm
