Like people, bacteria get invaded by viruses. In bacteria, the viral invaders are called bacteriophages, derived from the ...

Bacteria Use CRISPR to Recognize Themselves April 14, 2015. Immune systems from an array of organisms have been intently studied by scientists for decades, often with ...

Before humans repurposed it as a gene editing tool, CRISPR/Cas9 was a sort of internal immune system bacteria use to defend themselves against phages. Scientists have found that the 'scissors ...

While it once proved a technical challenge, scientists are now using CRISPR to turn bacteria into disease- and climate change-fighting microbes.

Bacteria use CRISPR-Cas systems as adaptive immune systems to withstand attacks from enemies like viruses. These systems have been adapted by scientists to remove or cut and replace specific ...

These bacteria can be vulnerable to infection from viruses called bacteriophages. One of bacterial cells' most well-known defenses against these viruses is the CRISPR system, which evolved in ...

In recent years, the gene-editing tool CRISPR/Cas9 has been applied to a wide variety of different organisms and has started a biomedical revolution. The method was created using a defense technique ...

The appeal of using CRISPR is that such drugs would be very specific—theoretically, they would kill a single species of germ while leaving beneficial bacteria intact.

When bacteria grab viral DNA, they always insert new sequences after old ones, so the CRISPR system naturally orders information from newest to oldest. Shipman’s team took advantage of that.

Now, researchers have developed a way to manipulate key assembly line enzymes in bacteria, using CRISPR-Cas9 gene editing, which could pave the way to production of a new generation of complex ...

Scientists have demonstrated a new potential way to edit the genomes of bacteria in complex environments, by equipping viruses to hunt them down and insert the CRISPR gene-editing system.
