redbluered and vestal you are so right that discovering new antibiotics isn't going to solve this issue.
Don't understand this at all.
We are in am arms race with bacteria - so surely having more and a wider range of AB is going to help.
Obviously if we tacked the practises that help develop resistance in bacteria to AB and the one that then lead to these getting spread - we will have more resiatnant for longer.

In 2012, antibiotic development continues to stagnate. Two systemic antibacterial agents have been approved for use in humans by the U.S. FDA from 2008 through the current year. Compare that to sixteen that were approved from 1983-1987. In particular, we have had no new classes of antibiotics to treat Gram-negative bacilli (GNB) for more than 40 years – amazingly, the fluoroquinolones were the last new class of antibiotics to treat GNB. Meanwhile, antibiotic resistance continues to spread like wildfire, particularly among the GNB. The U.S. and global healthcare systems are encountering on a regular basis extensively drug-resistant (XDR) organisms resistant to all antibiotics except for colistin, a highly toxic agent of questionable efficacy whose use was abandoned in the 1960s when safer and more effective therapies became available.
Even worse, we are seeing pan drug-resistant (PDR) organisms, resistant to all available antibiotics, including colistin. Examples of XDR and PDR bacteria that plague the US and global healthcare systems include carbapenem-resistant bacteria, such as KPC Klebsiella and Acinetobacter. Both of these organisms are increasingly XDR, and are causing increasing infections in the US and worldwide. These infections cause high death rates despite available therapy. They will continue to kill a high percentage of infected patients until new prevention and treatment methods become available.
Twelve years ago, Nobel Laureate Dr. Joshua Lederberg wrote that “The future of humanity and microbes will likely evolve…as episodes of our wits versus their genes.” In the 12 years since Dr. Lederberg wrote those prescient words, we have witnessed a continued expansion of antibiotic resistant pathogens due to their genes. Amazingly, we seem to have stopped trying to use our wits to keep up. So, why is this?
There are three principal causes of the antibiotic market failure. The first is scientific: the low-hanging fruit have been plucked. Drug screens for new antibiotics tend to re-discover the same lead compounds over and over again. There have been more than 100 antibacterial agents developed for use in humans in the U.S. since sulfonamides. Each new generation that has come to us has raised the bar for what is necessary to discover and develop the next generation. Thus, discovery and development of antibiotics has become scientifically more complex, more expensive, and more time consuming over time. The second cause is economic: antibiotics represent a poor return on investment relative to other classes of drugs. The third cause is regulatory: the pathways to antibiotic approval through the U.S. FDA have become confusing, generally infeasible, and questionably relevant to patients and providers over the past decade.
