Herbicide Caused Antibiotic Resistance Not Regulated

(Beyond Pesticides, November 21, 2017) Both the active and inert ingredients in common herbicides induce antibiotic resistance in human pathogenic bacteria, according to the latest research from New Zealand scientists, published in Microbiology this week.  Previous research from the same team found in 2015 that commercial formulations of Roundup (containing glyphosate and inert ingredients) and Kamba (containing 2,4-D, Dicamba, and inert ingredients) caused antibiotic resistance to develop in Salmonella eterica and Escherichia coli, but this new research drills down into what ingredients in these formulations resulted in the effect. Lead author of the study, Jack Heinemann, PhD, University Canterbury’s School of Biological Sciences, explains that ultimately this research indicates that, “The sub-lethal effects of industrially manufactured chemical products should be considered by regulators when deciding whether the products are safe for their intended use,” Scientists parsed out the effects of individual active and inert ingredients by obtaining pure, technical grade dicamba, 2,4-D, and glyphosate, as well as the inert co-formulants “Tween80” and “CMC,” which are respectively, used to reduce surface tension and regulate the viscosity in a formulated herbicide, though also used as emulsifiers in foods like ice cream and in medicines. The technical grade herbicides were first applied to […]

Western Australian Researchers Mine Antimalarial Compounds as Potential Herbicides

(Beyond Pesticides, July 12, 2017) In a move that threatens to further the spread of antibiotic resistance, researchers at the University of Western Australia (UWA) mining a collection of antimalarial drugs for potential new herbicides. Joshua Mylne, PhD, a senior lecturer in the School of Molecular Sciences (SMS) who directs the project, got started based on work he did while in the Australian Army Reserve. There he discovered that “malarial parasites are actually closely related to plants.” Due to widespread resistance of weeds to the popular herbicide glyphosate, Dr. Mylne began investigating antimalarial drugs as potential replacements. Malaria parasites are actually protozoans in the genus Plasmodium. Their crucial connection with plants is that the parasite contains a plastid similar to the chloroplast in plants. Like the chloroplast in plants, this plastid is critical for the survival of the parasite. Along with organic chemist Keith Stubbs, PhD, associate professor in SMS, Dr. Mylne began screening chemicals in the “Malaria Box,” an open source collection of potential anti-malarial drugs that have never been commercialized. Of the 20 chemicals tested on the small weed Arabidopsis thaliana, 11 were found to have some herbicidal activity. They were then compared to the herbicides glyphosate, glufosinate, asulam, […]
