A bacteriophage that overcomes the bacterial CRISPR/Cas immune system by interrupting the CRISPR DNA with its own genome
Microbe of the episode:
In this study, a phage is discovered that inserts its own genome into the CRISPR/Cas sequence in the bacterial genome, disrupting the bacterial defenses. To escape the defenses while it is doing this insertion, it carries genes for previously-unknown anti-CRISPR proteins. But inserting and removing a viral sequence from the bacterial genome is not always a clean procedure.
