Of HCV have been amplified and sequenced utilizing the approaches we recently described.12,13 To avoid feasible carryover contaminations, common procedures were taken.30 The resulting p38β list sequences have been then analyzed employing the BioEdit software program.31 Prior to tree building, the best-fitting substitution model was selected utilizing jModeltest depending on the Akaike Facts Criterion (AIC).32 Consistent with our recent results, GTR +I+ was located to be the ideal for all datasets.11 Under this model, ML trees were heuristically searched by SPR and NNI perturbation algorithms implemented in PHYML.33 Together with the tree files generated, ML tree topology was displayed utilizing the MEGA5 program.AcknowledgmentsFunding: The study was supported by a grant from NIAID/NIH (5 R01 AI080734-03A).REFERENCE1.
