“[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 ...

Viruses, then, may have existed before bacteria, archaea, or eukaryotes (Figure 4; Prangishvili et al. 2006). Most biologists now agree that the very first replicating molecules consisted of RNA ...

Researchers at Rutgers University found that the viruses consisted of bacteria while others belonged to archaea - a single-cell organism similar to bacteria - which requires extreme environments ...

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, ...
