Abstract Carnivore protoparvovirus 1 includes feline parvovirus (FPV), variants of canine parvovirus‐2 (CPV‐2), mink enteritis virus, and raccoon parvovirus, important pathogens affecting both wild and domestic carnivores. In this report, we described a fatal CPV‐2 infection in a rescued Taiwanese pangolin, which provides the first evidence of CPV‐2 infection in a non‐carnivore. Post‐rescue, the Taiwanese pangolin died from complications resulting from a severe panleucocytopenia and bloody diarrhoea. A full autopsy was performed and microscopic examination of the tissues revealed ulcerative, necrotizing, and haemorrhagic glossitis, esophagitis and enteritis. The results of transmission electronic microscopy, polymerase chain reaction and in situ hybridization provided confirmatory evidence that the lesions in the tongue, oesophagus and intestine were associated with a protoparvovirus. Phylogenetic comparison of the whole VP2 gene from the current pangolin protoparvovirus strain showed close clustering with the CPV‐2c strains from domestic dogs in Taiwan, China and Singapore. The amino acid sequence of the pangolin protoparvovirus showed 100% identity to the CPV‐2c strains from domestic dogs in China, Italy, and Singapore. The current findings highlight that pangolins are susceptible to protoparvoviruses. The potential of cross‐species transmission of protoparvoviruses between Carnivora and Pholidota should be considered when housing pangolins in close proximity to carnivores and adopting strict biosecurity measures to avoid cross‐species transmission in rescue facilities and zoos.
