Although New World Camelids (NWC) are not ruminants but are assigned to Tylopoda, they are susceptible to a number of viral pathogens that are important for ruminants, such as Bovine Herpesvirus 1 (BHV-1), Bovine Viral Diarrhoea Virus (BVDV), Schmallenberg Virus (SBV) and Bluetongue Virus (BTV). They should thus be considered as carriers and reservoirs of these viruses. We report a comprehensive prevalence study to assess the role of NWC as potential carriers of four viral pathogens and to estimate the potential risk of infection of other farm animals, especially ruminants. In this study, 447 serum samples from 186 llamas and 261 alpacas were collected, representative of the entire country of Austria. The samples were examined using ELISA, Serum Neutralisation Test (SNT) and PCR. One sample was positive for BHV-1 antibodies (0.2%), one was positive for BVDV antibodies (0.2%), none were positive for BVDV nucleic acids (0%), 323 were positive for SBV antibodies (67.7%) and 53 were positive for BTV antibodies (11.8%). In summary, the two viruses BVDV and BHV-1 currently have a minor role in Austria and the risk that NWC may infect farm animals can be considered low. A relatively high number of NWC were seropositive for BTV and SBV. NWC may act as a reservoir for BTV and SBV and have an important role in the transmission of these viruses.
