A New Picornavirus Isolated from Ectropis oblique

  • Available online: 20 February 2004
  • A new picorna-like virus was isolated from dead Evtropis oblique larvae deceased from NPV infection. Electron microscopic observations of purified virions were non-enveloped isometric particles with diameter of 26nm. The virions contain two capsid proteins: 31.5kDa and 28.8kDa, the amount of later is 2.5 times more than that of the former. Analysis of 3′terminal sequence of EoPV clone identified that it can encode RdRp and has eight conserved motifs. Homology analysis shows that it is closely related to Perina nuda picorna-like virus. All of these properties indicate that this virus should be a member of Picornaviridae.

    Abstract: A new picorna-like virus was isolated from dead Evtropis oblique larvae deceased from NPV infection. Electron microscopic observations of purified virions were non-enveloped isometric particles with diameter of 26nm. The virions contain two capsid proteins: 31.5kDa and 28.8kDa, the amount of later is 2.5 times more than that of the former. Analysis of 3′terminal sequence of EoPV clone identified that it can encode RdRp and has eight conserved motifs. Homology analysis shows that it is closely related to Perina nuda picorna-like virus. All of these properties indicate that this virus should be a member of Picornaviridae.
