Figure 1

Phylogenetic relationship between Romanian and Brazilian subtype F nucleotide sequences. The tree was constructed by using the neighbor joining method included in the Phylipi 3.5c package (7). Three hundred and two aligned nucleotides from the envelope C2-V3 region were used for analysis. The vertical distance between the branches is noninformative and for clarity only. Numbers at the branch nodes indicate bootstrap values. The nucleotide sequence distance among strains can be deduced by using t
