“[It] implies that certain microbial populations are much more susceptible to virus activity in these deep ocean regions,” he added. Deep-sea ecosystems cover more than 65 percent of the world’s ...

The genomes of giant viruses, such as the recently discovered Mimivirus that infects amoebae, are larger than the genomes of many bacteria and some archaea (Raoult & Forterre 2008). Viruses ...

The majority of these viruses infect microbes, including bacteria, archaea, and microeukaryotes, all of which are vital players in the global fixation and cycling of key elements such as carbon, ...

Another popular theory states that viruses evolved from degenerated bacteria or archaea that lost most of the genetic instructions for carrying out metabolism and forming cells. There are many ...

likely from a group of complex microbes called Asgard archaea — and we inherited two defense proteins that fight off viruses ...

Though fungi make up a tiny part of the human microbiome, they play an important role in both the prevention and development of many diseases.

The human microbiome comprises bacteria, archaea, viruses, and eukaryotes which reside within and outside our bodies. These organisms impact human physiology, both in health and in disease ...
