Virus phylogeny. The complete env and pol coding regions were sequenced for each virus isolate (EMBL accession numbers: env; AM279343ā€“AM279369 and pol; AM279370ā€“AM279396). Subsequently, NJ-trees were constructed and tree topology was assessed by bootstrap analysis. The SIVcpzGAB sequence was used to root the tree. Ten isolates were found to group with the CRF02_AG reference strains, five were subtype A and five were subtype G.
