Effect of infection by P. multocida on the thickness of the epithelial cell layer. Differentiated bovine airway epithelial cells were infected by P. multocida at the indicated inoculation conditions (102 or 105 CFU; 1 or 4 h) and immune-stained as described in Figure 3. A Vertical sections of the immunostained samples; B relative thickness of the epithelial cell layer compared to mock infected samples. Scale bars, 50 µm.
