Figure 1

EHV5 antigen expression 72 hpi in localized cell clusters within EHV5-inoculated lung explants. In the upper panel, cryosections were stained for EHV5 antigens (Sultan; green) and cell nuclei (Hoechst 33342; blue). In the lower panel, cryosections were simultaneously stained for EHV5 antigens (Sultan; green), cytokeratin (AE1/AE3; red) and cell nuclei (Hoechst 33342; blue). The scale bars represent 50 µm.
