Transmission of Hepatitis C Virus to Several Organ and Tissue Recipients from an Antibody-Negative Donor

Figure 2. Each branch represents a different viral sequence, and small distances between branches suggest genetic relatedness.
Sequences belonging to each NHANES III participant and a recipient known to have been infected before transplantation are
marked by separate shaded regions. The size of each shaded region represents the genetic diversity of quasi-species from that
specimen or group of specimens. Isolates belonging to the donor and 8 case-patients are clustered together.
Unrooted phylogenetic tree of hypervariable region sequences of graft donor, graft recipients, and selected Third National
Health and Nutrition Examination Survey (NHANES III) participants, United States, 2000–2002.
