Identification of a gammaherpesvirus belonging to the malignant catarrhal fever group of viruses in Pyrenean chamois (Rupicapra p. pyrenaica)

© 2016, Springer-Verlag Wien. 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.
