Pyrenean chamois (Rupicapra pyrenaica) populations of the central and eastern Pyrenees have been affected by severe outbreaks associated with Border disease virus (BDV) since 2001. Eight Pyrenean chamois (7 males and 1 female) from 1 to 8 years of age with clinical signs consistent with BDV infection were studied. At necropsy, whole blood, tissue samples (skin, brain, prescapular lymph node, thyroid gland, lung, liver, spleen, kidney, small intestine, bone marrow, and testicle), urine, and nasal, oral, and rectal swabs were obtained. The fetus from a pregnant female was also studied. Reverse transcription polymerase chain reaction (RT-PCR) was used to detect the virus in all samples, and virus isolation was performed. Sera and tissue samples were positive to RT-PCR, and the virus was isolated from all chamois. The nasal, oral, and rectal swabs and urine samples were RT-PCR positive in 100%, 85.71%, 71.43%, and 100% of chamois, respectively, confirming the excretion of the virus via these 4 routes. In addition, sera were tested for BDV antibodies using enzyme-linked immunosorbent assay and seroneutralization techniques, with negative results. Sequence analysis of the 59 untranslated region in 7 of the chamois confirmed that the virus is grouped into the BDV-4 genotype, the same BDV previously described in Pyrenean chamois. To the authors' knowledge, this is the first study of naturally infected Pyrenean chamois, providing evidence that infected animals shed BDV through nasal, oral, fecal, and urinary excretion routes.
