• The family Hepadnaviridae comprises 2 genera ( Orthohepadnavirus and Avihepadnavirus ), and viruses classified within these genera have a narrow host range. (cdc.gov)
  • Orthohepadnavirus , which infect mammals, and Avihepadnavirus , which infect birds ( 1 ). (cdc.gov)
  • The divergence of orthohepadnavirus and also avihepadnavirus took place ~ 125,000 years ago (95% interval 78,297- 313,500). (healthbeacon.co.uk)
  • Avihepadnavirus is a genus of viruses, in the family Hepadnaviridae. (wikipedia.org)
  • Group: ssRNA-RT Order: Unassigned Family: Hepadnaviridae Genus: Avihepadnavirus Duck hepatitis B virus Heron hepatitis B virus Viruses in Avihepadnavirus are enveloped, with spherical geometries, and T=4 symmetry. (wikipedia.org)
  • Viruses in the genus Avihepadnavirus are enveloped, with spherical geometries, and T=4 symmetry. (wikipedia.org)
  • Genus Tequatrovirus ( T4virus , T4-ähnliche Viren , en. (wikipedia.org)
  • Phylogenetic analysis showed that ETHBV clustered within the genus Avihepadnavirus , forming a new clade ( Figure , panel A). The organization of the ETHBV genome was similar to other avian HBVs because all 3 overlapping ORFs (polymerase, nucleocapsid [preC/C] and presurface [preS/S] antigen) and several essential sequence motifs (e.g., the epsilon element, TATA boxes, and direct repeat sites DR1 and DR2) were identified ( Technical Appendix Figure 1).

  • Avihepadnavirus Template:Taxobox end Hepadnaviruses are a family of viruses which can cause liver infections in humans and animals. (wikidoc.org)
  • Both the Avihepadnavirus as well as Orthohepadna viruses began to expand about 25,000 years back. (healthbeacon.co.uk)
  • Avihepadnavirus Diversity in Parrots is Comparable to that Found Amongst all Other Avian Species. (sanbi.ac.za)
  • Resumen Objetivo: Describir las expansiones temporal y geográfica de la circulación del virus Zika en países y territorios, desde su aislamiento hasta 2018. (bvsalud.org)
  • Resultados: Desde su aislamiento en 1947 la circulación del virus Zika se expandió por África, Asia y el Pacífico hasta llegar a América en 2013, causando manifestaciones clínicas graves. (bvsalud.org)
  • Conclusión: La expansión de la circulación del virus Zika en las Américas fue la más amplia ya registrada, posiblemente como resultado de características poblacionales y geográficas de los lugares por donde el virus circuló. (bvsalud.org)
