Short Communication Complete genome analysis of hepatitis C virus subtypes 6t and 6u

Hepatitis C virus (HCV) genomes exhibit high nucleotide sequence diversity. In this study, weperformed complete genome sequence analysis of 11 HCV genotype 6 samples from Vietnamand Thailand. We identified nine HCV complete genomes belonging to subtypes 6a (D9), 6e(D42 and D88), 6f (TH52), 6i (TH24), 6l (D33), 6n (TH22 and TH31) and 6o (D85). Phylogeneticanalysis of the core/E1 and NS5B regions from unclassified genotype 6 isolates from Asianimmigrants in Canada revealed that two other viruses (D49 and D83) could be classified as novelcandidates of HCV subtypes 6t and 6u.
