FIG 3.

Phylogeny inferred by maximum-likelihood analysis obtained by alignment of 335 nucleotides covering the partial glycoprotein B (gB) gene region of BoHV-4 (A) and 200 nucleotides covering the partial thymidine kinase (TK) gene region of BoHV-4 (B). The phylogenetic tree includes the novel BoHV-4 isolate (TO-1, red rhombus) and sequences available in GenBank. Country of origin and collection date, when available, are indicated together with the accession number for each sequence. Bootstrap (1,000 replicates) values of >50 are shown at the internal nodes. The length of each pair of branches represents the distance between sequence pairs. The scale bar represents the percentage of nucleotide differences.
