when flesh eating bacteria feed off a host and the host dies, what happens to the parasite? does it continue to live or how does it eventually die?

Necrotizing fasciitis: There are several types of bacteria that can cause this but most commonly it is Strep Pyogenes that enter the body through a break in the skin. Unlike virus, bacteria live outside the body for a very long time and can survive without food or water by forming spores. Well after a fatal infection, the bacteria survives in the area to infect another who comes in contact with it.
