I think that the challenge we have is that today&#x27;s antibiotics are really like the proverbial &quot;sledgehammer to crack a nut&quot;.<p>There hasn&#x27;t been a great deal of interest in discovering new antibiotics, as this extract from Wikipedia describes:<p><pre><code>  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
</code></pre>
I assume that there isn&#x27;t much interest due to the limited financial rewards to the pharmaceutical industry.<p>What is really needed is a new way to target the truly &quot; foreign &quot; 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 &quot;carpet bombing&quot; methods we have today.
