What is idiophage?

Answer 1

An idiophage is something that eats itself. I assume there's almost nothing that does that in a healthy state.

Answer 2

Idiophage is a term sometimes used to describe a type of phage that specifically infects and targets individual strains or species of bacteria. These phages have a narrow host range, meaning they can only infect certain bacterial strains, as opposed to broad-spectrum phages that can infect a wider array of bacteria.
