Glyphosate and Dicamba Herbicides Increase Antibiotic Resistance in Bacteria

Oct 13 2018 –  by Sustainable Pulse

A new study has found that some of the world’s most widely used herbicides, Roundup (glyphosate) and Kamba (dicamba), increase the rate of antibiotic resistance development in bacteria by a factor of up to 100,000 times faster than occurs without the herbicide.

Both herbicides are used on GM crops engineered to tolerate them.

The new study adds to a growing body of evidence that herbicides used on a mass industrial scale, but not intended to be antibiotics, can have profound effects on bacteria, with potentially negative implications for medicine’s ability to treat infectious diseases caused by bacteria. University of Canterbury (New Zealand) Professor Jack Heinemann, one of the study’s authors, said, “The combination of chemicals to which bacteria are exposed in the modern environment should be addressed alongside antibiotic use if we are to preserve antibiotics in the long-term.”

An important finding of the new study was that even in cases where the herbicides increase the toxicity of antibiotics they also significantly increased the rate of antibiotic resistance, which the authors say could be contributing to the greater use of antibiotics in both agriculture and medicine.

Previously these researchers found that exposures to the herbicide products Roundup, Kamba and 2,4-D or the active ingredients alone most often increased resistance, but sometimes increased the susceptibility of potential human pathogens such as Salmonella enterica and Escherichia coli, depending on the antibiotic.

Prof Heinemann said, “We are inclined to think that when a drug or other chemical makes antibiotics more potent, that should be a good thing. But it also makes the antibiotic more effective at promoting resistance when the antibiotic is at lower concentrations, as we more often find in the environment. Such combinations can be like trying to put out the raging fire of antibiotic resistance with gasoline.”

The authors concluded that neither reducing the use of antibiotics nor the discovery of new ones may be sufficient strategies to avoid the post-antibiotic era. This is because bacteria may be exposed to other non-antibiotic chemicals that predispose them to evolve resistance to antibiotics more quickly. Herbicides are examples of some of the most common non-antibiotic chemicals in frequent global use. Thus antibiotic resistance may increase even if total antibiotic use is reduced, and new ones are invented, unless other environmental exposures are also controlled.

The new paper, “Agrichemicals and antibiotics in combination increase antibiotic resistance evolution” is published online in the peer-reviewed journal PeerJ on October 12 and can be downloaded without charge from here.

Documentary: In Search of Balance (5 min preview) “ It’s All Connected “

An exploration of a new paradigm of health, science, and medicine, based on the interconnections between us and nature.

At a genetic level, humans are literally connected to the rest of the natural world through our DNA. But today’s highly processed foods, pesticide based mono-culture farming methods, increasing urbanization, obsession with technology and destruction of the natural environment distance us further and further from the world we co-evolved with. We are out of balance with nature and the reductionist philosophy of modern western medicine, once immensely powerful, seems inadequate to answer today’s challenges.

Bacteria Resistant to all Treatments – Natural Allopathic Medicine to the Rescue

The mainstream media reports it like this: “The rise of the superbug is happening right now — and our last defense has just begun to collapse. The world is on the brink of an antibiotic apocalypse. A new dark age of medicine looms.

Natural Allopathic Medicine offers humanity a fighting chance against antibiotic resistant infections because they attack bacteria, viruses and fungus infections in a very different way.

What a Gatherer-Hunter Diet Did to a Man’s Gut in Just Three Days

After eating with the Hadza for just three days, Spector — who already had very healthy/diverse gut flora for a civilized person — increased his microbe diversity by 20 percent, an astonishing improvement. Not surprisingly, his gut flora balance returned to what it was before when he returned home.
