  1. Braun U, Hilbe M, Peterhans E, Schweizer M. Border disease in cattle. Vet J. 2019;246:12-20 pubmed publisher
    ..Interspecies transmission of BDV between sheep and cattle occurs regularly, but BDV in cattle appears to be of minor general importance. Nevertheless, BDV outbreaks at farm or local level can be very costly. ..

    ..Thus, it appears that the calves of the two production labels did not suffer obvious stress. This finding notwithstanding, all veal calves deserve to be reared under optimised animal-appropriate welfare conditions. ..

  4. Braun U, Frei S, Schweizer M, Zanoni R, Janett F. Short communication: Transmission of border disease virus to seronegative cows inseminated with infected semen. Res Vet Sci. 2015;100:297-8 pubmed publisher
    ..In the SNT, all cows had distinctly positive titres against BD virus. Therefore, BD virus is readily transmitted by infected semen, but none of the cows conceived, most likely because of poor semen quality. ..
  5. Braun U, Janett F, Züblin S, von Büren M, Hilbe M, Zanoni R, et al. Insemination with border disease virus-infected semen results in seroconversion in cows but not persistent infection in fetuses. BMC Vet Res. 2018;14:159 pubmed publisher
    ..The findings showed that cows inseminated with BDV-infected semen seroconverted and fetuses thus produced were not persistently infected. Transmission of BDV to cattle through infected semen, therefore, seems to be of minor importance. ..
  6. Braun U, Attiger J, Brammertz C. Ultrasonographic examination of the spinal cord and collection of cerebrospinal fluid from the atlanto-occipital space in cattle. BMC Vet Res. 2015;11:227 pubmed publisher
    ..Ultrasonographic findings and results of CSF analysis were similar in group B. Ultrasonography is useful for the visualisation of the spinal cord and facilitates the safe collection of CSF from the atlanto-occipital space in cattle. ..
