Bacteria are prokaryotic cells, and some infect single-celled eukaryotes such as amoeba, but as symbionts that benefit the amoeba by shielding them from viruses. Right now, giant viruses are not ...

Amoebae receive surprising support in defense against viruses: The bacteria they are infected with prevent them from being destroyed by giant viruses. Microbiologists have investigated how a virus ...

He and his team have continued to take frozen amoeba-infecting viruses from the permafrost soil layer and bring them back to an infectious stage. The most ancient of these viruses, based on carbon ...

Bacteria that protect against viruses influence food webs. Protists are widespread - living in waters, seawater and seabeds, among other places.

Scientists revived a 48,500-year-old "zombie" virus from permafrost and found it to be infectious.; The virus was tested on amoebas but could indicate more dangerous viruses are lurking in permafrost.

Viruses are tiny. Even compared to the smallest bacteria, which can be about 200 nanometers (a nanometer being one-billionth of a meter) in diameter, viruses are still teeny tiny, with the ...

Amoebae receive surprising support in defense against viruses: The bacteria they are infected with prevent them from being destroyed by giant viruses. A research team led by microbiologist ...
