Gut microbiome manipulation could result from virus discovery

Scientists have discovered how a common virus in the human gut infects and takes over bacterial cells—a finding that could be used to control the composition of the gut microbiome, which is important for human health.

How viruses and bacteria balance each other in the gut microbiome

The adage 'all things in moderation' applies not to just to food and drink, but also to the legions of bacteria inside our guts helping us digest that food and drink. It turns out the rule may also extend to the lesser understood ...

Overlooked: The role of bacterial viruses in plant health

We know how important bacteria and fungi are for the health of plants. In marine environments and in our own gut, bacteriophages (viruses that infect bacteria) are important in regulating the microbiome. Yet, their effect ...

MetaviralSPAdes—New assembler for virus genomes

When a new virus emerges, biologists rush to reconstruct its genome—a prerequisite for future diagnostic and vaccine development. The challenge with viral sequencing during an outbreak is that a sample from a patient, like ...

Bacteria uses viral weapon against other bacteria

Bacterial cells use both a virus—traditionally thought to be an enemy—and a prehistoric viral protein to kill other bacteria that competes with it for food according to an international team of researchers who believe ...

Bacteria harness viruses to distinguish friend from foe

Bacterial cells that normally colonize our guts can distinguish themselves from other bacterial species using what's traditionally considered their enemy—a virus. Researchers report April 16 in the journal Cell Reports ...
