Immunohistochemistry against the SRLV gag-P25 protein (mouse monoclonal anti-P25 antibody). Nasal mucosa was sampled 48 h post-inoculation from a lamb inoculated with rSeV-GFP-P25. A Marked immunoreactivity of ciliated epithelial cells and inflammatory cells in the submucosa (arrows). B Image analysis results are shown in blue for the studied areas and in red for the immunolabelled cells. C Strong labelling in the apical part of the cilia and cytoplasm of the macrophages/dendritic cells of the submucosa (thin arrow). D Image analysis results are shown in blue for the studied areas and in red for the immunolabelled cells.
