Presented at SEVPAC 2008 – Permission granted for use on SEVPAC website only

12  Sequencing of the amplification product produced 97% homology with reported sequences derived from Equine herpesvirus-5 (EHV-5)  Herdmates are seronegative for EHV-1 and BHV-1, which have been reported in camelids  EHV-1 => neurological signs and blindness 1  BHV-1 => fatal pneumonia 2  1 House JA, Gregg DA, Lubroth j, et al.
