University-industry Partnerships can help tackle Antibiotic Resistant Bacteria

An academic-industrial partnership published last January in the prestigious journal Nature the results of the development of antibiotic teixobactin. The reported work is still at an early preclinical stage but it is nevertheless good news. Over the last decades the introduction of new antibiotics has slowed down nearly to a halt and over the same period we have seen a dangerous increase in antibiotic resistant bacteria.

Such is the magnitude of the problem that it has attracted the attention of the U.S. government. Accepting several recommendations presented by the President’s Council of Advisors on Science and Technology (PCAST) in their comprehensive report, the Obama Administration issued last September an Executive Order establishing an interagency Task Force for combating antibiotic resistant bacteria and directing the Secretary of Human and Health Services (HHS) to establish an Advisory Council on this matter. More recently the White House issued a strategic plan to tackle this problem.

Etiology of Antibiotic Resistance

Infectious diseases have been a major cause of morbidity and mortality from time immemorial. The early discovery of sulfa drugs in the 1930s and then antibiotics in the 1940s significantly aided the fight against these scourges. Following World War II society experienced extraordinary gains in life expectancy and overall quality of life. During that period, marked by optimism, many people presumed victory over infectious diseases. However, overuse of antibiotics and a slowdown of innovation, allowed bacteria to develop resistance at such a pace that some experts now speak of a post-antibiotic era.

The problem is manifold: overuse of antibiotics, slow innovation, and bacterial evolution.

The overuse of antibiotics in both humans and livestock also facilitated the emergence of antibiotic resistant bacteria. Responsibility falls to health care providers who prescribed antibiotics liberally and patients who did not complete their prescribed dosages. Acknowledging this problem, the medical community has been training physicians to avoid pressures to prescribe antibiotics for children (and their parents) with infections that are likely to be viral in origin. Educational efforts are also underway to encourage patients to complete their full course of every prescribed antibiotic and not to halt treatment when symptoms ease. The excessive use of antibiotics in food-producing animals is perhaps less manageable because it affects the bottom line of farm operations. For instance, the FDA reported that even though famers were aware of the risks, antibiotics use in feedstock increased by 16 percent from 2009 to 2012.

The development of antibiotics—perhaps a more adequate term would be anti-bacterial agents—indirectly contributed to the problem by being incremental and by nearly stalling two decades ago. Many revolutionary innovations in antibiotics were introduced in a first period of development that started in the 1940s and lasted about two decades. Building upon scaffolds and mechanisms discovered theretofore, a second period of incremental development followed over three decades, through to 1990s, with roughly three new antibiotics introduced every year. High competition and little differentiations rendered antibiotics less and less profitable and over a third period covering the last 20 years pharmaceutical companies have cut development of new antibiotics down to a trickle.

The misguided overuse and misuse of antibiotics together with the economics of antibiotic innovation compounded the problem taking place in nature: bacteria evolves and adapts rapidly.
