Since then, a handful of
other giant virus groups have been found.
Some small viruses, called «virophages» help their hosts protecting against
other giant viruses.

Dubbed Klosneuviruses, the
giant virus contains a more complete set of translation machinery genes than any
other virus known to date.
Scientists typically don't classify
viruses as living organisms, but
giant viruses like these, with their own protein - making machinery and
other functions normally carried out in living cells, blur the lines between what's alive and what isn't.
But after discovering a novel group of
giant viruses with a more complete set of translation machinery genes than any
other virus known to date, scientists at the U.S. Department of Energy Joint Genome Institute (DOE JGI), a DOE Office of Science User Facility, believe that this group (dubbed «Klosneuviruses») significantly increases our understanding of viral evolution.
Including information about
other viruses and
virus - like elements: adenoviruses that infect animals and are one of the causes of the common cold; certain bacteriophages that infect bacteria; transpovirons which infect
giant viruses; and a Tetrahymena transposable element (Tlr1), the
virus «evolutionary tree» appears as a network of swapped genes.
The recent discovery of virophages inside the
giant viruses, which in turn infect amoeba, has led to speculation about their origin and their relationship to
other viruses and small transposable genetic elements.
Claverie and Abergel have helped to discover
