5 ways to save antibiotics
Dec. 14, 2010 By Ron Najafi TheScientist
Here’s what we need to do to create new antibiotics and extend the life of those that already exist
The world is facing a crisis: Bacteria have become more and more resistant to virtually all existing antibiotics, yet many companies are abandoning the field in favor of more lucrative medicines.

People are proposing various solutions, such as offering financial incentives to the pharmaceutical industry to spur the development of vitally needed antibiotics. But along with creating new drugs, we can get more life from our existing antibiotics and maintain their utility. As the head of a company focused on the development of compounds to treat and prevent a wide range of infections without causing bacterial resistance, this is an issue I find both fascinating and vitally important. In my opinion, there are five ways we can extend the functional life of our antibiotic arsenal.
1. Do the obvious
In a recent New York Times article, Ramanan Laxminarayan, director of the Extending the Cure project on antibiotic resistance at the policy organization Resources for the Future, suggested that the government should focus on conserving the effectiveness of existing antibiotics by preventing their unnecessary use in people and farm animals, and by requiring better infection control measures in hospitals.
These are crucial steps, which should be taken immediately. First, we must stop and assess the use of antibiotics as additives to the feed of our farm animals, and specifically prevent the unnecessary use of antibiotics in animals that are not sick. The U.S. Congress has already urged farmers to stop the overuse of antibiotics in animals because it is creating new, drug-resistant strains of bacteria that can spread to humans. A recent CBS news report spotlighted microbiologist Stuart Levy at Tufts University, the individual who identified tetracycline resistance in chickens more than 30 years ago. In his research, nearly all of the E. coli in the intestinal tracts of the chickens become tetracycline-resistant after one week of treatment.
US: First GM Plants Found in the Wild
August 6, 2010 Care2
This is the stuff of my nightmares: Genetically-modified (GM) plants escaping the confines of agriculture and invading the wild. We thought regular invasive species were bad? They seem tame compared to genetic contamination of the wild. Even more alarming: Some of the plants had a mix of modified genes, indicating that they are reproducing on their own.
Although GM plant populations in the wild have been found in Canada, this is the first time they have been found in the United Sates.
Meredith G. Schafer, from the University of Arkansas, and colleagues established transects of land over 3000 miles long including interstate, state and county roads in North Dakota from which they collected, photographed and tested 406 canola plants.
The results show that transgenic plants have clearly established populations in the wild. Of the 406 plants collected, 347 tested positive for CP4 EPSPS protein (resistant to glyphosate herbicide, aka Roundup) or PAT protein (resistant to glufosinate herbicide, aka LibertyLink). The finding shows that genetically modified canola plants can survive and thrive in the wild perhaps for decades–the study was presented today at the annual meeting of the Ecological Society of America.
The team’s key finding was two plants that each carried both types of herbicide resistance — a combination that is not commercially available. The only way this can happen in the wild is if the plants are reproducing on their own. “There were two instances of multiple transgenes in single individuals,” said coauthor Cynthia Sagers, University of Arkansas. “Varieties with multiple transgenic traits have not yet been released commercially, so this finding suggests that feral populations are reproducing and have become established outside of cultivation. These observations have important implications for the ecology and management of native and weedy species, as well as for the management of biotech products in the U.S.”
Once a GM crop is released it cannot be unreleased, and there are no systems in place to prevent genetic contamination through pollen flow, spills or human error. Although the GM plants found by the roadside are assumed to be the result of escaped seeds during transportation, the GM plants found away from roads suggest that the plants are taking on a life of their own.
Stop Global Food Security Act Promoting GMOs
Biotech corporations and mega-charities are promoting the GMO agenda as US foreign policy, and it must be stopped.

The GM clause to food security
The US Global Food Security Act of 2009 (S. 384) sponsored by Richard Lugar (Indiana, Republican), Robert Casey (Pennsylvania, Democrat) and seven other US Senators in February 2009 is [1, 2] “A bill to authorize appropriations for fiscal years 2010 through 2014 to provide assistance to foreign countries to promote food security, to stimulate rural economies, and to improve emergency response to food crises, to amend the Foreign Assistance Act of 1961, and for other purposes.”
However, the proposed amendment to the Foreign Assistance Act (FAA) of 1961 has proven controversial. It would “include research on biotechnological advances appropriate to local ecological conditions, including genetically modified technology.”
The bill is supported by the US land grant colleges as well as InterAction (American Council for Voluntary International Action) and its 26 member organizations including WWF, Oxfam, Bread for the World CARE, Save the Children, and ONE [3]. The bill was passed through the Senate foreign Relations Committee on 31 March 2009, and the Senate is expected to vote on it soon in 2010.
Widespread opposition to GM mandate
In April 2010, 140 civil society groups, scientists, and development experts signed an open letter to US Senators, urging them to “strip the GM mandate” from the Global Food Security Act [4]. While the petitioners applaud the bill’s intention to reform aid programmes to focus on longer-term agricultural development and restructure aid agencies to better respond to crises, they object to the clause effectively earmarking one agricultural technology – genetic modification – for billions of dollars in federal funding. US$7.7 billion goes with the bill, and no other farming methods or technologies are mentioned.
Not surprisingly, Monsanto has lobbied the hardest to support the bill. The US company is the world’s leader in the increasingly concentrated agricultural biotech industry, which is already subject to an anti-trust inquiry (see [5] US Farmers Oppose ‘Big Ag’ in Anti-Trust Hearing, SiS 46). Monsanto is likely to benefit most from the new research funding stream, and to profit from its patented products (both GM seeds and pesticides).
The petitioning groups represent the anti-hunger, family farms, farm-workers, consumers and those practicing and supporting sustainable agriculture. The letter delivered urges the Senate to reject the bill until it is made technology-neutral, and calls for agricultural research funding to concentrate on addressing local challenges faced by small-scale farmers, instead of mandating a specific and narrow technological fix, particularly one with little prospect of success and increasingly rejected by countries around the world.
