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." ...

Along with colleagues, they established that CRISPR-Cas systems provide adaptive immunity against viruses in bacteria where it recognizes foreign DNA and uses a special molecular scalpel to target ...

Like any other organism, bacteria are constantly exposed to pathogenic threats, such as viruses and plasmids. The Aviram Lab is interested in understanding how bacterial cells protect themselves from ...
