Figure 2From: Selection of hepatitis C virus resistant to ribavirinHCV recovered from ribavirin treated cells is resistant to ribavirin. J6/JFH1 and HCV-RR1 were serially passaged in Huh7D cells in medium containing the indicated concentration of ribavirin; at each passage HCV titers in the supernatants were obtained as described in the text. Titers are expressed as the mean number of foci of each of four replicates. Error bars represent the standard deviation.Back to article page
