Population characterization of horse #9807 viral envelope gp90 sequences. A phylogenetic tree of aligned deduced amino acid sequences was constructed by the neighbor joining method from Kimura corrected distances with the optimality criterion set to distance. The tree was unrooted. Bootstrap values were determined over 1000 iterations and are indicated at the nodes of the branches. Branch lengths are proportional to the distance existing between the sequences. C"#", EIAVPA clone number; WYO, Wyoming; PV, EIAVPV; CHVax, Chinese vaccine stain.
