FIG. 2.

Breakpoint analyses of mosaic viruses. For each single genome sequence the region of the amplicon that is CRF19 (white), the region that is subtype B (dark gray), and the region within which the putative breakpoint lies (light gray) are depicted. Sequences with overlapping breakpoint regions are grouped together and the results of time points 85 and 87 weeks postdiagnosis are combined. The number of times each sequence variant is detected at that time point is indicated on the right of each bar representing the sequence variant. The RT start codon is indicated with a filled triangle and the black lines indicate drug resistance mutations defined using the Stanford University HIV drug resistance database. The dotted line indicates that not all grouped sequences contain the specified drug resistance mutation. The numbers above and below the bars indicate HXB2 nucleotide numbering.
