Fig. 5From: A putative HIV-1 subtype C/CRF11_cpx unique recombinant from South AfricaMaximum likelihood phylogenetic analysis of the integrase sequence of 08MB26ZA. The sequence is not delineated as either related to HIV-1 subtype C or CRF11_cpx reference sequences. Bootstrap values above 70 % are shown. The tree is rooted with group O sequences. The scale represents the number of base substitutions per siteBack to article page
