3D stereoscopic anaglyph (view with red-green or red-cyan glasses) of a Rabies virus particle. Rabies is an extremely dangerous disease, often transmitted by the bite of an infected animal such as a dog or a bat. The virus particle shown here is a typical bullet shape and is covered by glycoprotein spikes. The spikes insert into the lipid membrane or viral envelope. Below the membrane lies the helical nucleoprotein. This contains the viral RNA.
