FIG. 2.

Phylogenetic analysis of plasma and PBMC HCV variants infecting patient 3. HCV RNA was amplified between nucleotides 100 and 1600 in plasma and PBMC and then cloned. The phylogenetic trees drawn from 5′-UTR sequences (nucleotides 100 to 350) (A) and the E1-E2 region (nucleotides 1370 to 1600) (B) evidenced the same clustering of some PBMC HCV variants that could be assigned to subtype 1a while other variants were assigned to subtype 1b.
