Merhaba!

As I mentioned in another answer, bacteria should be removed from the host body after the medical task is completed, therefore another concept, which is named termination switches, could be also added to bacteria to terminate them after they had carried out their task through laser-triggered hyperthermia, antibiotics or bacterial lysis. If no such mechanism to remove them is in place, you would expect them to be neutralized by the immune system (granted that they are below a pathological dose). Since they are of cellular material, they are also fully biodegradable.

All the best,
