  1. Neutralizing titers were calculated according to the Spearman-Kärber method as the serum dilution necessary to neutralize the cytopathic effect in 50% of the wells (effective dose 50%; ED50) and are presented as the mean values for each virus titration (samples classified as negative in ELISA are excluded). Virus back titrations for the reindeer and caribou neutralizations oscillated between 90 and 115 TCID50, (90 for CvHV1, 95 for BoHV1, 110 for ElkHV and 115 for CvHV2).
