    I wonder if there will be a time when we have developed such a library of antibiotics and the bacteria evolving to deactivate the latest one but earlier ones work again.

    It seems to me with a large enough library of antibiotics and serums, bacteria, germs and viruses would be left in a cycle where the time comes when a pathogen evolves a defense for the latest, then we find the earliest ones start working again, like Penicillin acts like it did in the 1940's and becomes a miracle drug again.

    Pathogens following the same path they did in that round of drug resistance, so we can always keep up without having to develop thousands of new anti whatever drugs.

    It seems this latest development may be a step along that path.
