Summary of lung pathology post mock- or B. pertussis -inoculation. H&E stained slides were examined for alveolitis, perivasculitis and hypertrophy of mucus-producing glands. Lung lesions were scored semi-quantitatively as absent (0), minimal (1), slight (2), moderate (3), marked (4), or severe (5) per type of lesion and added up to calculate the pathology-score (range 0–15). Dots represent the pathology score per individual mouse, horizontal lines represent the groups median.
