Serums from 270 llamas representing 21 farms throughout Oregon were
obtained and assayed for antibody levels against viruses of livestock. These viral
diseases included: bovine viral diarrhea (BVD), bovine herpesvirus 1 (BHV-1),
parainfluenza-3 (PI-3), bovine respiratory syncytial virus (BRSV), bovine adenovirus
species 3 (BA3), equine herpesvirus 1 (EHV-1), equine adenovirus (EA), equine
influenza, subtypes 1 and 2 (EI-1, EI-2), equine viral arteritis (EVA), ovine
progressive pneumonia (OPP), bluetongue (BT), vesicular stomatitis, New Jersey
strain and Indiana strain (VSV-NJ, VSV-IN), and llama adenovirus strain 7649
(LA7649). Antibodies to Ehrlichia risticii (ER), the rickettsia) organism causing
Potomac horse fever (PHF), were also assayed.
Of the 270 llamas, 252 had antibodies to LA7649. A total of 60 llamas
possessed antibodies to various viruses associated with livestock disease. Seven of
these llamas had antibodies to more than one virus (excluding LA7649). Forty three
exhibited antibodies to EA, 12 to BVD, and 12 to PI-3. Four had antibodies to BTV,
2 to BHV-1, and 2 to EI-1. One had antibodies to EI-2, one to EHV-1, and one to
BRSV. All 270 llamas lacked antibodies to EVA, BA3, VSV-NJ, VSV-IN, OPP and ER.
Presence and type of livestock were noted on each farm. Whether a llama was
born on the farm or purchased and the length of time the llama had been on the farm
was also noted. / Graduation date: 1993
