The purpose of the present study was to evaluate the use of enzyme-linked immunosorbent assay (ELISA) antigen detection in blood or fetal fluids and reverse transcription polymerase chain reaction (RT-PCR) amplification in tissues for routine laboratory diagnosis of Border disease virus (BDV) infection. Samples from 67 fetuses, 6 stillbirths, and 11 lambs from 25 commercial flocks with suspicion of BDV abortion and 3 fetuses, 7 stillbirths, and 15 lambs obtained from an experimental infection with a local isolate (BDV genotype 4) were investigated. Presence of BDV was detected by RT-PCR in 7.9% of fetuses, 50% of stillbirths, and 50% of lambs from the commercial flocks analyzed, corresponding to 8 of the 25 farms (32%). A similar percentage of the lambs and stillbirths from the experimental infection were positive by RT-PCR of tissue samples (54.5%), and the highest positivity was detected in lymph node, thyroid gland, and kidney. The current study revealed that RT-PCR analysis of stillbirths and lambs with clinical symptoms is more suitable than the analysis of fetuses to confirm the presence of BDV in a flock. Pestiviral antigen was detected by antigen ELISA in a high proportion of fetuses (24/58) and stillbirths (3/4) from commercial flocks, but in lambs, the presence of colostral antibodies masked the detection of the antigen by ELISA. Nevertheless, in lambs from the experimental infection that were not fed colostrum, antigen ELISA was less efficient than RT-PCR in detecting viral presence in stillbirths and lambs. Antigen ELISA is therefore recommended for fetuses with advanced autolysis that can adversely affect RNA integrity.

Since 2001, severe outbreaks of disease associated with border disease virus (BDV) infection have been reported in Pyrenean chamois. The disease is characterized by variable degrees of cachexia, alopecia and neurological manifestations prior to death. The aim of this study was to investigate this disease under experimental conditions. To assess viral virulence, humoral immune response, dissemination and probable routes of transmission, seven chamois (five seronegative and two seropositive for BDV) were inoculated with a BDV isolated from a naturally infected chamois. A group of three chamois were maintained as uninfected controls. The five seronegative chamois became viraemic from day 2 post-inoculation (p.i.) until their death (three animals) or the end of the experiment (on day 34 p.i.) and developed neutralizing antibodies from day 18 p.i. until the end of the study. Continuous shedding of the virus was detected by RT-PCR in oral, nasal and rectal swabs in viraemic chamois from day 5 p.i. Despite none of the viraemic chamois showing obvious neurological signs, all of them had a non-suppurative meningoencephalitis as seen in naturally infected chamois. The two inoculated BDV-seropositive chamois did not become viraemic. This study confirms that BDV is the primary agent of the disease that has been affecting chamois populations in recent years in the Pyrenees and that previously acquired humoral immunity is protective.
