Not an issue but just wondering. If you have greebles resistant to one antibiotic (AB) and you knock them off using another one can you then go back to the original AB as they are all dead now or doesnt it work like that.

I am very aware of taking the whole lot, as an aside, lack of AB saved Europe, one of the Ottoman Sultans who was about to take the whole lot died from an infected boil.

Doesn’t work like that. The bug may still be present but not causing infection e.g. MRSA.
