The epithelial membrane gets degenerated and liberates nucleocapsids
into the cytoplasm.
7) Flaviviruses are single-stranded, positive-sense RNA viruses with icosahedral nucleocapsids
The effectiveness and versatility of the newly developed methods will be tested on two viral nucleocapsids
of different architectures, the icosahedral capsid of non-tailed bacteriophage AP205 and the filamentous, helical nucleocapsid
of Measles virus.
It is also reported that the nucleocapsids
of Morbilliviruses attach with lymphocytes of their natural hosts and induce an immunosuppression (Kerdiles et al.
DISCUSSION: Flaviviruses are icosahedral nucleocapsids
surrounded by an envelope and a single-stranded, positive-polarity RNA genome.
Nascent particles are formed when the helical nucleocapsids
align along cytoplasmic membranes of the budding compartment (the membrane region between the rough endoplasmic reticulum and the Golgi complex), and virions obtain their membranes by budding into the cisternal lumen.
WSSV virions are enveloped, rod-shaped nucleocapsids
with a bacilliform to ovoid or ellipsoid shape (22).
The virions were enveloped and measured approximately 300 nm in length and had brick-shaped nucleocapsids
with a biconcave core.
were sometimes penetrated by stain (although the intact envelope was impermeable to stain) 100-110 nm in diameter.
25] In two other cases of otosclerosis, McKenna et al also observed on electron microscopy filamentous structures that were morphologically very similar to paramyxoviral nucleocapsids
Baculoviruses occlude their nucleocapsids
in polyhedral shaped OBs that may carry over 100 virions (nucleopolyhedroviruses, NPVs, genera Alphabaculovirus specific for lepidopteran, Gammabaculovirus specific for hymenopteran, and Deltabaculovirus specific for dipteran) or in granular OBs carrying only one virion (granuloviruses, GV, genus Betabaculovirus specific for lepidopteran) (Jehle et al.
The virions were surrounded by the glycoprotein spikes, and the individual nucleocapsids
inside the virions were seen as thin threads (when cut longitudinally) or dark dot-like figures (when cut in cross-section) and measured [approximately equal to]8 nm in diameter (Figure 1, panels B and C).
