A thorough understanding of virus diversity in wildlife provides epidemiological baseline information about pathogens.

In this study, eye swab samples were obtained from semi-domesticated reindeer (Rangifer tarandus tarandus) in

Norway during an outbreak of infectious eye disease, possibly a very early stage of infectious keratoconjunctivitis

(IKC). Large scale molecular virus screening, based on host nucleic acid depletion, sequence-independent

amplification and next-generation sequencing of partially purified viral nucleic acid, revealed the presence of a new

papillomavirus in 2 out of 8 eye swab samples and a new betaherpesvirus in 3 out of 8 eye swab samples collected

from animals with clinical signs and not in similar samples in 9 animals without clinical signs. Whether either virus

was responsible for causing the clinical signs or in any respect was associated to the disease condition remains to be
