A captive breeding programme for the Fennoscandian Arctic fox (Vulpes lagopus; syn. Alopex lagopus) failed due to fatal encephalitis. The aim of this study was to identify the causative agent. Viral nucleic acid was detected by PCR and in situ hybridization in the brain of affected foxes. The results suggest that a herpesvirus might be the causative agent. Whether this infection also occurs in free-living Arctic foxes is unknown. (C) 2011 Elsevier Ltd. All rights reserved.
