Management of Ocular Human herpesvirus 1 Infection in a White-faced Saki Monkey (Pithecia pithecia)

Résumé fourni par la source

A 20-y-old male intact white-faced saki monkey (Pithecia pithecia) presented with an acute ocular disease of the right eye. Clinical signs included periocular swelling, conjunctivitis, and anisocoria with a miotic right pupil. Conjunctival swabs were positive for Human herpesvirus 1 (HHV1) according to PCR amplification with sequencing. Initial clinical signs resolved with supportive treatment, and the animal was managed chronically by using acyclovir (5 mg/kg PO twice daily) during flare-ups. After more than 2 y, the progression of clinical disease led to enucleation of the right eye. At 2 mo after surgery, acute presentation of severe neurologic signs, including ataxia and blindness, resulted in euthanasia. Histopathology, PCR analysis, and sequencing results were consistent with viral encephalitis due to HHV1; coinfection with Pithecia pithecia lymphocryptovirus 1 was identified. This report describes the first case of managed HHV1 infection in a platyrrhine primate and the first case of HHV1 in a white-faced saki monkey that was not rapidly fatal.
