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