Picture of the Day: The Ebola Virus


Poster «The Ebola Virus»

The Ebola virus and it’s close relative the Marburg virus are members of the Filoviridae family. These viruses are the causative agents of severe hemorrhagic fever, a disease with a fatality rate of up to 90%. The Ebola virus infects mainly the capillary endothelium and several types of immune cells. The symptoms of Ebola infection include maculopapular rash, petechiae, purpura, ecchymoses, dehydration and hematomas.

Since Ebola was first described in 1976, there have been several epidemics of this disease. Hundreds of people have died because of Ebola infections, mainly in Zaire, Sudan, Congo and Uganda. In addition, several fatalities have occurred because of accidents in laboratories working with the virus. Currently, a number of scientists claim that terrorists may use Ebola as a biological weapon.

In the 3D model presented in this study, Ebola-encoded structures are shown in maroon, and structures from human cells are shown in grey. The Ebola model is based on X-ray analysis, NMR spectroscopy, and general virology data published in the last two decades. Some protein structures were predicted using computational biology techniques, such as molecular modeling.

The Ebola virion is rod-shaped or 6-shaped, is 80 nm in diameter and up to 1,400 nm in length. In comparison, the diameter of HIV is 100–120 nm.

Testimonial

Visual Science’s Ebola Poster represents a pinnacle in the history of visualization of the human body. While it is true that the poster’s informative and instructional functions take priority over artistic intent, the latter is the firm foundation upon which this captivating image derives its mesmerizing qualities that captivates viewers.
Molecular modeling through computer graphics permits plenty of latitude for exercising artistic talent to inform, explain and instruct. Visual Science shows the way with its high quality, accurate, informative graphics that explain even the most complex processes of life.
