Despite the occurrence of clinical disease in a wide range of carnivore hosts, only vague accounts of clinical canine parvovirus type 2 (CPV-2) in any otter species have been reported in the literature. Over the course of 25 days, nine Asian small-clawed otters (Aonyx cinerea) presented for evaluation of inappetence, lethargy, vomiting, and diarrhea. A diagnosis of canine parvovirus type 2c was made based on electron microscopy, polymerase chain reaction, and DNA sequencing of group fecal samples. Supportive care was provided based on individual clinical assessment and included subcutaneous crystalline fluid therapy, antiemetics, antibiotics, appetite stimulants, and a neuraminidase inhibitor. Five of the nine otters exhibited moderate to severe disease requiring treatment, and one case was fatal despite supportive efforts. In light of this case report, CPV-2 should be recognized as a potential cause of gastrointestinal disease in Asian small-clawed otters.
