Bovine coronavirus (BCoV) is associated with three distinct clinical syndromes in cattle that is, neonatal diarrhoea, haemorrhagic diarrhoea in adults (the so‐called winter dysentery syndrome, WD) and respiratory infections in cattle of different ages. In addition, bovine‐like CoVs have been detected in various species including domestic and wild ruminants. However, bovine‐like CoVs have not been reported so far in odd‐toed ungulates. We describe an outbreak of WD associated with a bovine‐like CoV affecting several captive wild ungulates, including Indonesian tapirs (Acrocodia indica) an odd‐toed ungulate species (Perissodactyla) which, with even‐toed ungulates species (Artiodactyla) form the clade Euungulata. Genomic characterization of the CoV revealed that it was closely related to BCoVs previously reported in America. This case illustrates the adaptability of bovine‐like CoVs to new species and the necessity of continued surveillance of bovine‐like CoVs in various species.
