Abstract

Hepatitis G virus (HGV) isolates obtained from 20 Myanmarese and 10 Vietnamese subjects were analyzed. A cluster of isolates not belonging to any known genotype of HGV was found in five Myanmarese subjects and three Vietnamese subjects by phylogenetic analysis, and we classified this new genotype as type 4. These results revealed that the HGV genome can be classified into at least four major genotypes.

FIG. 1
Alignment of nucleotide sequences of the HGV 5′ UTR isolated from Myanmarese and Vietnamese subjects. Sources of all isolates with the accession numbers are described in the text. The nucleotide positions are based on those of the HGV PNF2161 isolate. Dashes indicate nucleotides that are identical to the top sequence (HGV PNF2161), and deletions of nucleotides are indicated by slashes. USA, United States.
