This report describes the genetic and antigenic variability of bovine viral diarrhea virus strains isolated in Belgium. Part of the 5’ untranslated region and the 5’ end of the gp53 (E2) coding sequence were amplified by PCR and sequenced. Phylogenetic analysis showed that most field isolates segregated into genotypes Ib or II. Only one out of 28 field isolates belonged to genotype Ia. Interestingly, some type I strains were equally divergent from types Ia and Ib strains and clustered into additional subtypes within genotype I. Immune sera from young calves experimentally inoculated with fi…
