Fig. 2From: Characterization update of HIV-1 M subtypes diversity and proposal for subtypes A and D sub-subtypes reclassificationSubtypes A (a) and D (b) near full genome sequences maximum likelihood phylogenetic trees. Names of all sub-subtypes are indicated according to the new classification proposal. For all identified sub-subtypes and the other major clades, i.e. subtypes, nodes presenting a branch support > 95% (bootstrap analysis using 1000 replicates) are indicated by an asteriskBack to article page
