The maximum clade credibility (MCC) tree was estimated by Bayesian analysis of 170 NS5B sequences with 313 bp of Hepatitis C virus strains. The posterior probabilities of the key nodes are depicted above the respective nodes. The twenty-two sequences from Rondônia were highlighted: Six sequences subtype 1a (red), eleven sequences subtype 1b (blue), three sequenced subtype 2b (dark blue) and two sequences subtype 3a (green).
