Phylogenetic analysis of HIV IN nucleotide sequences from drug naive patients from northeastern South Africa. The tree was generated by the neighbor-joining method and shows the test sequences (in bold face) clustering and intermingling with reference HIV-1 subtype C integrase sequences previously documented from Southern Africa and elsewhere. Virus 08BBVCT28ZA could not be definitely assigned.
