Only two truly new (new mechanism of action) antibiotics have been developed in the last 30-40 years.  A number of new antibiotics were approved in the 80&#x27;s and 90&#x27;s, but I wouldn&#x27;t say people thought we had won the war.<p>The really challenging thing with antibiotics (as a reply below notes) is that if you create a great new antibiotic, nobody will use it unless they have to.<p>There is resistance out there, but for most infections, the 40+ year old antibiotics work just fine.  It&#x27;s not like almost every other disease where the best drug gets used first line.<p>Unless the financial incentives are fixed, it&#x27;s unlikely there will be enough incentive to do the R&amp;D to create new antibiotics.
