Roundup 'Weedkiller' Feeds Antibiotic Resistant Bacteria, Study Finds

The nightmarish toxicological profile of Roundup herbicide (glyphosate) continues to emerge within the peer-reviewed research, this time revealing its role in supporting the growth of a pathogenic bacteria of great medical significance.
A concerning new study published in the Brazilian Journal of Microbiology titled, "Influence of glyphosate in planktonic and biofilm growth of Pseudomonas aeruginosa," indicates that the world's most widely used herbicide Roundup (glyphosate) may be contributing to the enhanced growth of the pathogenic bacteria P. aeruginosa in our environment.
The Brazilian team responsible for the study expressed concern over the "virtual nonexistence" of research evaluating glyphosate herbicide-pathogenic microbiota interactions, and conducted a series of microbial experiments to fill this data gap. They noted:
P. aeruginosa is commonly found in watercourses and reservoirs in both oxygen (aerobic) and non-oxygen preferring forms (anaerobic), and can be a source of waterborne infection.
The results of the new study indicate that when exposed to varying concentrations of both glyphosate (a common contaminant found in GM agricultural runoff) and oxygen, both the aerobic the anaerobic and biofilm forming strains of this bacteria can thrive:
The researchers also focused on the ability of glyphosate to support the growth of so-called biofilms, a closely adhering colony of bacteria embedded in a self-produced matrix of a "slimy" extracellular polymeric substance (EPS), revealing:
