Evaluation of three commercial bovine ELISA kits for detection of antibodies against Alphaherpesviruses in reindeer (Rangifer tarandus tarandus)

摘要

BackgroundThe genus Varicellovirus (family Herpesviridae subfamily Alphaherpesvirinae) includes a group of viruses genetically and antigenically related to bovine herpesvirus 1 (BoHV-1) among which cervid herpesvirus 2 (CvHV-2) can be of importance in reindeer. These viruses are known to be responsible for different diseases in both wild and domestic animals. Reindeer are a keystone in the indigenous Saami culture and previous studies have reported the presence of antibodies against alphaherpesviruses in semi-domesticated reindeer in northern Norway. Mortality rates, especially in calves, can be very high in some herds and the abortion potential of alphaherpesvirus in reindeer, unlike in bovines, remains unknown.ELISA kits are the most used screening method in domestic ruminants and given the close genetic relationship between viruses within this genus, it might be possible to use such kits to screen cervids for different alphaherpesviruses. We have compared three different commercial ELISA kits in order to validate its use for reindeer and CvHV-2.
