RESUMEN
High prevalence (46 %) of a gammaherpesvirus was confirmed by molecular detection in the lungs of hunted Pyrenean chamois. The partial glycoprotein B sequence up to the DNA polymerase gene showed 96.6 % nucleotide sequence identity to the Rupicapra rupicapra gammaherpesvirus 1 and 81.5 % to ovine herpesvirus 2. This novel sequence clusters within sequences derived from the malignant catarrhal fever group of viruses, and the corresponding virus is tentatively named Rupicapra pyrenaica gammaherpesvirus 1 (RpHV-1). No specific histological lesions were associated with RpHV-1, nor were any detrimental effects on host health. The epidemiological, phylogenetic and histopathological results suggest that Pyrenean chamois is the natural host of RpHV-1.

The bladderworm Pearsonema (syn Capillaria) plica affects domestic dogs and wild carnivores worldwide. A high prevalence in red foxes (Vulpes vulpes) has been reported in many European countries. P. plica inhabits the lower urinary tract and is considered to be of low pathogenic significance in dogs mostly causing asymptomatic infections. However, a higher level of pathogenicity has been reported in foxes. A severe cystitis associated with numerous bladderworms was found in a captive arctic fox (Vulpes lagopus) originating from the endangered Fennoscandian arctic fox population. To our knowledge this is the first description of P. plica infection in an arctic fox.
