Ebola Viruses

Abstract

A small group of exotic and mysterious viral agents that cause a severe haemorrhagic disease in human and/or nonhuman primates.

Keywords: Ebola virus; filovirus; haemorrhagic fever; ribonucleic acid

Figure 1.

Ebola virus (Zaire species) genomic RNA. Coding regions for seven linearly arranged genes are shown as hatched boxes. The scale at the bottom of the figure indicates units of sequence length numbered in kilobases. IR, intergenic region.

Figure 2.

Organization and expression of the glycoprotein genes of Ebola viruses, showing the production of the secreted SGP homodimer as the primary gene product from an unedited transcript, and the structural GP trimer through a transcriptional editing event (single adenosine insertion).
