Bacteria get invaded by viruses called phages. Scientists are studying how bacteria use CRISPR to defend themselves from phages, which will inform new phage-based treatments for bacterial infections ...

Cat1 monomers seen here in shades of pink and purple, while cA4 glueing the dimers to extend the filament are in orange. Every living creature on Earth needs to protect itself from things that would ...

Bacteria combat phage infection using antiphage systems and many systems generate nucleotide-derived second messengers upon infection that activate effector proteins to mediate immunity. Phages ...

Some viruses, known as bacteriophages, only infect bacterial cells, often destroying those bacteria in the process. Bacteria, in turn, can develop defenses against these viruses. Bacteriophages or ...

Jumbo phages belong to a group of viruses that attack bacteria. They inject their DNA and then reproduce by taking over the cell’s DNA-copying machinery. Eventually, a phage makes so many copies of ...

Like people, bacteria get invaded by viruses. In bacteria, the viral invaders are called bacteriophages, derived from the Greek word for bacteria-eaters, or in shortened form, "phages." Scientists ...

Phage therapy is an emerging strategy that uses viruses that target bacteria to restore gut balance and treat microbiome-related diseases. Ongoing research and early trials show promise, but ...

Scientists identify a new CARF effector, Cat1, with a complex structure that depletes a key metabolite, halting viral replication by cutting off its energy supply. (Nanowerk News) Every living ...
