A team of scientists affiliated with several research facilities in France has conducted a study on giant viruses known as mimiviruses and has found that at least some of them have an immune system that is similar in some ways to CRISPR in bacteria. In their paper published in the journal Nature, the team describes the genetic study they undertook of multiple strains of mimiviruses looking to understand why some of them appeared to have immunity to a particular kind of virophage infection while others did not.
