Phylogenetic analysis. Phylogenetic analysis of the isolated viruses based on the highly variable SU portion of env encompassing the SU4 and SU5 regions [16, 17]. The tree was constructed by the neighbor-joining method, and bootstrap values (1000 replicates) above 70% are considered to be significant. * designates the two SRLV A4 isolates described previously [14].
