Figure 1. Phylogenetic analysis the characteristic of HIV-1 natural resistance mutations in former paid blood donors in Henan Province.

Figure 1

The bootstrap values were performed by 5000, greater than 80 clusters shown in figure, black spots represent the drug-resistant mutations samples, black triangles represent the aggregation of the same cluster, reference strains for subtype B are: B.CN.2001.CNHN24.AY180905 and B.FR.1983.HXB2-LAI-IIIB-BRU.K03455.
