I think that the challenge we have is that today's antibiotics are really like the proverbial "sledgehammer to crack a nut". There hasn't been a great deal of interest in discovering new antibiotics, as this extract from Wikipedia describes: Following a 40-year hiatus in discovering new classes of antibacterial compounds, four new classes of antibacterial antibiotics have been brought into clinical use in the late 2000s and early 2010s I assume that there isn't much interest due to the limited financial rewards to the pharmaceutical industry. What is really needed is a new way to target the truly " foreign " and trouble making bacteria in the body, and eradicate it. Hopefully in the next 40 years we can make such a breakthrough and stop the "carpet bombing" methods we have today.
