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 ...

Multiple defense systems CRISPR is a mechanism in the adaptive immune systems of bacteria and other certain single-cell organisms that offers protection against viruses, called phages. The six ...

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." ...

CRISPR—Clustered Regularly Interspaced Short Palindromic Repeats—is the microbial world’s answer to adaptive immunity. Bacteria don’t generate antibodies when they are invaded by a ...

Bacteria have CRISPR-Cas so the phages have developed anti-CRISPRs, which enables them to block the immune complexes of the bacteria. "What we've discovered is a whole new way that phages can stop ...
