摘要

The genus Orbivirus of the family Reoviridae includes a genetically diverse group of dsRNA arthropod-borne viruses that infect a wide variety of animal species. Here, we report the complete genome and phylogenetic analysis of a novel orbivirus (IAn-66411 or Sathuvachari virus, SVIV) isolated in 1 963 from starlings (Brahminy myna) collected in Vellore, Tamil Nadu, India. Comparative genetic analysis of the SVIV polymerase (VP1 protein), core protein (VP3) and outer core protein (VP7) confirmed that SVIV is most closely related to the mosquito-borne orbiviruses, but that it is equally divergent from all known species. Therefore, SVIV should be tentatively considered as the prototype of a novel mosquito-associated Orbivirus species. These findings will aid in the development of molecular reagents that can identify genetically similar orbiviruses and Received 2 August 2012 help elucidate their geographical distribution, epidemiology, species tropism and possible disease Accepted 24 January 2013 association.
