Summary
An <a href="//commons.wikimedia.org/wiki/Electron_microscope" title="Electron microscope">electron micrograph</a> of an <a href="//commons.wikimedia.org/wiki/Ebola" title="Ebola">Ebola</a> viral particle showing the characteristic filamentous structure of a <a href="//commons.wikimedia.org/w/index.php?title=Filoviridae&action=edit&redlink=1" class="new" title="Filoviridae (page does not exist)">Filoviridae</a>. The viral filaments can appear in images in various shapes including a 'u', '6', a coil, or branched resulting in pleomorphic particles. The filaments are reported to be between 60-80 <a href="//commons.wikimedia.org/w/index.php?title=Nanometre&action=edit&redlink=1" class="new" title="Nanometre (page does not exist)">nm</a> in diameter, the length of a filament associated with an individual viral partial is extremely variable with Ebola particles of up to 14,000 nm in length being reported. An average length, which may represent the most infectious particles is in the region of 1000 nm.
The first electronmicrograph of Ebola was <a href="//commons.wikimedia.org/w/index.php?title=13_October&action=edit&redlink=1" class="new" title="13 October (page does not exist)">13 October</a> <a href="//commons.wikimedia.org/wiki/1976" title="1976">1976</a> by Dr. F.A.

The nucleocapsid structure consists of a central channel, 20-30nm in diameter, surrounded by helically wound <a href="//commons.wikimedia.org/w/index.php?title=Capsid&action=edit&redlink=1" class="new" title="Capsid (page does not exist)">capsid</a> with a diameter of 40-50nm and an interval of 5nm. 7nm <a href="//commons.wikimedia.org/w/index.php?title=Glycoprotein&action=edit&redlink=1" class="new" title="Glycoprotein (page does not exist)">glycoprotein</a> spikes spaced 10 nm apart from each other are present within the outer envelope of the virus which is derived from the host <a href="//commons.wikimedia.org/w/index.php?title=Cell_membrane&action=edit&redlink=1" class="new" title="Cell membrane (page does not exist)">cell membrane</a>. Each viral particle contains one molecule of single-stranded, negative-sense <a href="//commons.wikimedia.org/wiki/RNA" title="RNA">RNA</a>, which encodes the seven viral proteins.
