Blog Article

Avihepadnavirus is a genus of the Hepadnaviridae family.It primarily infects birds, including species of duck, geese, cranes, storks, and herons etc.To understand the genetic relatedness and evolutionary diversity among avihepadnavirus strains, Reduction Pulley With Bracket a comprehensive analysis of the available 136 full-length viral genomes (n = 136) was conducted.The genomes were classified into two major genotypes, i.

e., GI and GII.GI viruses were further classified into 8 sub-genotypes including DHBV-I (duck hepatitis B virus-I), DHBV-II (Snow goose Hepatitis B, SGHBV), DHBV-III, RGHBV (rossgoose hepatitis B virus), CHBV (crane hepatitis B virus), THBV (Tinamou hepatitis B virus), STHBV (stork hepatitis B virus), and HHBV (Heron hepatitis B virus).DHBV-I contains two sub-clades DHBV-Ia and DHBV-Ib.

Parrot hepatitis B virus (PHBV) stains fall into GII which appeared as a separate phylogenetic branch/clade.All the subtypes of viruses in GI and GII seem to be genetically connected with viruses of DHBV-I by multiple mutational steps in phylogeographic analysis.Furthermore, 16 potential recombination events among different sub-genotypes in GI and one in GII were identified, but none of which is inter-genotypic between GI and GII.Overall, the results provide a whole picture of the genetic relatedness of avihepadnavirus strains, which may assist in the surveillance of Tea Infuser virus spreading.
