Abstract
The prevalence of bovine viral diarrhea virus (BVDV) in persistently infected (PI) cattle in beef breeding herds was determined using 30 herds with 4530 calves. The samples were collected by ear notches and tested for BVDV antigens using immunohistochemistry (IHC) and antigen capture enzyme-linked immunosorbent assay (ACE). Animals with initial positives on both IHC and ACE were sampled again using both tests and serums were collected for viral propagation and sequencing of a viral genomic region, 5′-untranslated region (5′-UTR) for viral subtyping. Samples were also collected from the dams of PI calves. There were 25 PI calves from 4530 samples (0.55%) and these PI calves were from 5 of the 30 herds (16.7%). Two herds had multiple PI calves and 3 herds had only 1 PI calf. Only 1 of the 25 dams with a PI calf was also PI (4.0%). The subtype of all the PI isolates was BVDV1b. Histories of the ranches indicated 23 out of 30 had herd additions of untested breeding females. Twenty-four of the 30 herds had adult cowherd vaccinations against BVDV, primarily using killed BVDV vaccines at pregnancy examination.

Les échantillons ont été prélevés par encoches d’oreille et testés pour les antigènes du BVDV par immunohistochimie (IHC) et par test de capture antigénique immuno-enzymatique (ACE). Les animaux trouvés positifs par IHC et ACE lors du premier échantillonnage ont été éprouvés de nouveau à l’aide des deux tests, et des sérums ont été prélevés pour culture et séquençage d’une région génomique virale, la région 5′-non-traduite (5′-UTR), pour sous-typage viral. Des échantillons ont également été prélevés sur les mères des veaux PI. Il y avait 25 veaux PI parmi les 4530 échantillons (0,55 %) et ces veaux PI provenaient de 5 des 30 troupeaux (16,7 %). Deux troupeaux avaient plus de 1 veaux PI et 3 troupeaux avaient seulement 1 veau PI. Seulement 1 des 25 mères avec un veau PI était également PI (4,0 %). Le sous-type de tous les isolats était du BVDV1b. Le signalement des différentes fermes indiquait que 23 des 30 avaient fait des ajouts de femelles reproductrices non-éprouvées. Vingt-quatre des 30 fermes avaient un programme de vaccination des vaches adultes contre le BVDV, utilisant principalement un vaccin BVDV tué au moment des examens de gestation.</p><p>(Traduit par Docteur Serge Messier)</p></trans-abstract></article-meta></front></pmc><affiliations><list></list><tree><noCountry><name sortKey="Burge, Lurinda J" sort="Burge, Lurinda J" uniqKey="Burge L" first="Lurinda J." last="Burge">Lurinda J.
