Mast cells in the left cranial pulmonary lobe of colostrum-deprived neonatal calves were quantified 2 and 6 h after intrabronchial inoculation with Mannheimia (Pasteurella) haemolytica A1. The mast cells were detected (1) immunohistochemically with a mouse anti-human mast cell tryptase monoclonal antibody, and (2) by metachromatic staining with low pH toluidine blue. A greater number of mast cells was demonstrated by the second method than by the first. At 6 h after inoculation, but not at 2 h, the number of mast cells was significantly reduced at the site of the main lesions. Treatment of calves with a sialyl Lewis mimetic (TBC1269) did not appreciably affect the results at 6 h.
