World's largest virus found


A giant virus that lurks inside amoebas and may cause pneumonia in humans has been spotted by scientists. "Mimivirus" is the biggest virus found so far, and was discovered in a sample taken from a water cooling tower in Bradford, UK, in 1992.

It has at least 900 genes, an enormous number for a virus, and its size is more like that of a bacterium.

It can be spotted through a good optical microscope - most viruses can only be visualised by electron microscopes.
