Phylogenetic analysis of env sequences from different SRV-2 isolates. (A) A phylogenetic tree of reference SRV-1, SRV-2 and SRV-3 env protein sequences and sequences obtained from the SRV-2 isolates in this study (see Table 1) was generated from a ClustalW multiple alignment using the protein maximum-likelihood method as implemented in the Phylip package (v. 3.62). The sequence of the distantly related simian sarcoma virus (SSV) env protein was used as outgroup [Genbank:NC001514]. (B) A detailed phylogenetic tree of the SRV-2 reference and isolate sequences was similarly generated using SRV-3 as outgroup. Emerging clusters were labelled as subtypes SRV-2A through 2F and virus isolates from animals diagnosed with RF are indicated.
