a Maximum likelihood phylogenetic tree of the pol sequence of virus 08MB26ZA. The sequence is shown to cluster with CRF11_cpx reference sequences with a bootstrap value of 98 %. The tree is rooted with group O sequences. The scale represents the number of base substitutions per site. b Phylogenetic relationship of combined protease and reverse transcriptase fragments of the polymerase gene of 08MB26ZA. The fragment is assigned to CRF11_cpx with a high bootstrap value. The scale represents the number of base substitutions per site
