Of HCV have been amplified and sequenced using the approaches we lately described.12,13 To avoid feasible carryover contaminations, standard procedures had been taken.30 The resulting sequences had been then analyzed applying the BioEdit software program.31 Before tree building, the best-fitting substitution model was chosen working with jModeltest based on the Akaike Details Criterion (AIC).32 Constant with our current final results, GTR +I+ was found to be the top for all datasets.11 Below this model, ML trees were heuristically searched by SPR and NNI perturbation algorithms implemented in PHYML.33 With all the tree files generated, ML tree topology was displayed working with the MEGA5 system.AcknowledgmentsFunding: The study was supported by a grant from NIAID/NIH (five R01 AI080734-03A).REFERENCE1.
