These first microbes would have been extremely simple. But were they viruses or bacteria? Scientists don't have a conclusive ...

While these studies have told us a lot about how gut bacteria affect health, the viruses that make up the microbiome – the gut virome – are less commonly explored. Researchers from the ...

Now, researchers have found that a family of related proteins is used to fight viruses in organisms ranging from bacteria to humans. While the effects it triggers vary among organisms, it appears ...

Researchers uncover a notorious cholera strain that contains sophisticated immune systems to fend off viruses, which potentially helped it to fuel a devastating epidemic across Latin America.

Although bacteria and viruses are both too small to be seen without a microscope, they're as different as giraffes and goldfish. Bacteria are relatively complex, single-celled creatures ...

These viruses don’t go after us. Instead, they prey on bacteria and could help us fight antibiotic resistance. The findings are described in a study published October 9 in the journal Frontiers ...

My colleagues and I published a study showing how an immune system protein crucial to fighting against viruses also plays an indispensable role in fighting bacteria. How viral and bacterial ...

since most of the bacteria they identified were strains that originated in people’s mouths. This time, they turned their attention to viruses—and found the universe of phages. The good news is ...

This suggests that viruses could help bacteria adapt and coevolve to survive in nutrient-depleted man-made environments. Discover the latest in science, tech, and space with over 100,000 ...

This also protects bacteria from, say, antibiotics or from viruses that prey exclusively on bacteria. Such bacteria-infecting viruses, known as phages, are considered a possible alternative to ...
