The Antibacterial Resistance Threat: Are We Heading Toward a Post-Antibiotic Era?
Source: PEW Charitable Trusts The above graphic, from the Antibiotic Resistance Project by the PEW charitable trusts, summarizes how alarming the emergence of drug resistant bacterial strains has gotten over the past few decades. According to data from the Center for Disease Control (CDC), every year 2 million Americans acquire drug-resistant infections [1], in other words infections that do not respond to treatment with ordinary antibiotics. Not only do drug-resistant infections require much stronger drugs, but, when not deadly, they often leave patients with long-lasting complications. One of the scariest threats is carbapenem-resistant Enterobacteriaceae (CRE), bacteria that are resistant to several kinds of antibiotics. In 2001, only North Carolina, out of all 50 states had reported one CRE infection. Last year, in 2015, 48 states reported CRE infections to the CDC. And while drug-resistant strains emerge rapidly, the discovery of antimicrobial substances has stalled: in the last decade, only 9 new antibiotics were approved, compared to 29 discovered in the 1980s and 23 in the 1990s. We are fighting a new war, and we are running out of weapons. How does drug resistance emerge? Bacteria constitute an irreplaceable building block of our ecosystem: they are found in soil, water, air, and in every living organism. In humans, it's estimated that they outnumber our cells by 3:1, and numerous studies have shown that not only do they help us digest and produce enzymes t...
