Abstract

The genus Teschovirus consists of two species, Teschovirus A and Teschovirus B, with over 19 genotypes. This study sequenced the near-complete genomes of the PTV YC2 strain, previously isolated. Comparative analyses revealed nucleotide and amino acid homologies between PTV-YC2 and other PTV strains ranging from 69.7% to 93.2% and 75.6% to 99.0%, respectively. Genetic divergence analysis of the P1, polyprotein and 2C-3CD genes confirmed that PTV-YC2 belonged to the Teschovirus B species. Phylogenetic analyses showed a close evolutionary relationship between YC2 and the HuN42 strain, the prototype of the TV-B3 genotype, leading to PTV-YC2's categorization as TV-B3. This study is the first to document the prevalence of the TV-B3 genotype in Jiangxi Province, China.

中国江西省乙型肝炎病毒基因组特征的首次报道。
Teschovirus属由Teschovirus A和Teschovirus B两种组成,有超过19种基因型。这项研究对先前分离的PTV YC2菌株的近乎完整的基因组进行了测序。PTV- yc2与其他PTV菌株的核苷酸和氨基酸同源性分别为69.7% ~ 93.2%和75.6% ~ 99.0%。P1、polyprotein和2C-3CD基因的遗传差异分析证实PTV-YC2属于Teschovirus B种。系统发育分析表明,YC2与TV-B3基因型原型HuN42株进化关系密切,PTV-YC2可归类为TV-B3。本研究首次记录了TV-B3基因型在中国江西省的流行情况。
