Two major respiratory enveloped viruses (equine influenza virus [EIV] and equine arteritis virus [EAV]) were compared to the enveloped herpesvirus EHV1 in their susceptibility to eBD1, -2, and -3 during different steps in the infection of rabbit kidney (RK13) cells (by EAV and EHV1), Madin-Darby canine kidney (MDCK) cells (by EIV), or equine respiratory epithelial cells (EREC) (by EIV and EHV1). Here, COL7A1 is linked to infection.
