Morphological and Molecular Characterization
of a Cypovirus from the mosquito Uranotaenia sapphirina
A novel
cypovirus has been isolated from the dipterous insect Uranotaenia sapphirina
(UsCPV) and shown to cause a chronic infection confined to the living substance
of animal tissue cells of the stomachic ceca and posterior abdomen.
The
assembly of huge numbers of virions and inclusion bodies and their arrangement
into paracrystalline arrays provides the gut of infected insects a particular
blue brightness.
The virions
that were examined by microscopy square measure polyhedron (55 to sixty-five nm
in diameter) with a central core that's encircled by one capsid layer. they're
typically prepacked on an individual basis among blocky inclusion bodies
(polyhedra, ∼100 nm
across), though 2 to eight virus particles were generally occluded along.
The virus
was by experimentation transmitted per os to many dipterous insect species. The
transmission rate was increased by the presence of metallic element ions
however was strangled by metallic element ions.
Most of
the infected larvae survived to adulthood, and therefore the adults maintained
the infection.
Natural
action analysis of the UsCPV ordering segments (using 1 Chronicles agarose
gels) generated a migration pattern (electropherotype) that's totally different
from those of the sixteen Cypovirus species already recognized.
UsCPV
ordering phase ten (Seg-10) showed no vital ester sequence similarity to the corresponding phase of the opposite cypoviruses that have antecedently been
analyzed, and it's totally different “conserved” termini.
A BLAST search of the UsCPV deduced
aminoalkanoic acid sequence additionally showed very little similarity to
tusseh CPV-4 (67 of 290 [23%]) or Choristoneura fumiferana CPV-16 (33 of 111
[29%]).
We have a tendency to conclude that UsCPV ought to be recognized as a member of a brand
new Cypovirus species (Cypovirus seventeen, strain UsCPV-17).
