“…The intranasal inoculation of FHV-1 is a proven effective method to reproduce infection in mice since lesions and viral DNA can be found in the lungs as well as adjacent organs as demonstrated in cats (G. F. McGregor, Sheehan, & Simko, 2016) and in mice infected with EHV-1 (Mori et al, 2012). Such systemic infection in mice could also be detected for BoHV-5 (Mesquita et al, 2017), but the inoculation was performed intraperitoneally and with higher viral titers. Systemic disease is more likely to be caused by intraperitoneal or intravenous injections and, in contrast, peripheral infections have been initiated by ocular, vaginal, skin, and nasal/oral tissue inoculations (Kollias, Huneke, Wigdahl, & Jennings, 2015).…”
