Phylogenetic relationships between French and international sequences of BVDV-1 genotypes 1e and 1b. Maximum likelihood phylogenetic trees inferred from French and international sequences of genotypes (A) 1e and (B) 1b. Tips are coloured according to the sample continent or country of origin and sizes represent the number of closely related publicly available sequences (99.5% identity) from the same location. European countries with less than ten sequences were grouped under the location “Europe” in 1e phylogeny.
