Phylogenetic reconstruction of the 5’UTR of BVDV isolated of PI animals. Only 11/19 strains could be sequenced because of the quality of the DNA a) Maximum Likelihood (ML) phylogenetic analysis. The evolutionary history was derived using the method of ML based on the model of General Time-Reversible + Gamma Model. The analysis was performed with 26 nucleotide sequences and a total of 325 positions in the data set. Colombian isolates were grouped in the genotype 1 (Blue), (labeled with circles in pink) with a bootstrap of 1. b Sub genotyping the reference strains of BVDV 1 (from a to q) to assemble the tree were selected from the data set of the GenBank. Their accession numbers are included in the tree. These sequences were aligned with the 11 Colombian sequences. The evolutionary history was derived using the method of ML based on the model of General Time-Reversible Model GAMMA and validated using bootstrap analysis with 100 replicates. The analysis involved 28 nucleotide sequences. There were a total of 232 positions in the final dataset. Colombian isolates were grouped in the Subtype 1a (Blue), (labeled with circles in pink) with a bootstrap of 0.62
