Researchers have discovered a virus that can grow an immune system of its own and kill the bacteria that causes cholera.

The researchers discovered genes of a functional immune system that was limited only to some types of bacteria. The researchers found that only those viruses that have this type of immune system can kill the cholera causing bacteria.
“The immune system allows the phage to target and destroy specific inhibitory genes of the host cell by literally cutting the target genes into pieces. By disarming these genes, the phage essentially disarms the host cell, and can then proceed with the infection and kill the host cell”, lead researcher Kimberley Seed said.
